What Are The Fundamental Parts Of A Radar PCB?
You find the following parts in a radar PCB:
- A transmitter: You can employ a power amplifier as your transmitter in a radar PCB. A waveform generator generates the signal, which the power amplifies.
- Waveguides: Waveguides are transmission lines that allow you to transmit Radar signals.
- Antenna: You can employ planar arrays, parabolic reflector, or electronically steered phased arrays for your antenna.
- Duplexer: A duplexer is a device that allows an antenna to function as both a transmitter and a receiver. It could take a gaseous from which causes a short circuit at the receiver’s input when you turn on the transmitter.
- Receiver: This could be a super-heterodyne receiver or any other with a processor for signal detection and processing.
- Threshold Decision: To detect the existence of any object, you compare the receiver’s output to a threshold. You assume the existence of noise if the output falls below any threshold.

What Are The Important Aspects Of A Radar PCB?
You find the following aspects related to the radar PCB:
Range is the distance between the Radar and the target. A radar PCB sends a signal to the target which responds by sending an echo signal at light speed back.
Pulse Repetition Frequency
Delivery of radar signals should be at each clock pulse with an appropriately selected time interval between the two clock pulses.
It should be such that you receive the echo signal corresponding to the current clock pulse before the next clock pulse.
The radar PCB delivers a periodic signal characterized by a sequence of narrow rectangular pulses. Pulse repetition time is the time interval between consecutive clock pulses.
Pulse repetition frequency is the reciprocal of pulse repetition time. It is the frequency at which the radar PCB sends the signal.
Maximum Unambiguous Range
Every clock pulse should broadcast radar signals. You receive the return signal corresponding to the current clock pulse after the succeeding clock pulse. This is only if the interval between the two clock pulses is shorter.
Consequently, you note that the target’s range appears to be shorter than it actually is. You therefore have to carefully choose the time interval between the two clock pulses.
It should be so that you receive the echo signal corresponding to the current clock pulse before the succeeding pulse begins. This way, you receive the target’s true range, also known as the target’s maximum unambiguous range.
Consider the time the echo signal takes to arrive at the radar PCB after initial transmission from the pulse width. This is the target’s minimum range also known as the target’s shortest range.
Where Do You Find Radar PCBs?
The following include some of the common applications of a radar PCB:
Radar PCBs find use in air defense systems for locating and identifying targets and guiding weapons to hit such targets. Additionally, you find radar PCBs employed in missile guiding systems as well as enemy identification on navigational maps.

Ground Traffic Control
Traffic police employ equipment with radar PCBs to monitor vehicle speeds and in general traffic management to control congestion.
Radar PCB has allowed the safe navigation of space locomotives to safely land. Also, we can track satellites and monitor planetary systems and features such as meteors using equipment with radar PCB.
Military Radar PCB
What Are Some Of The Types Of Radar PCB You Can Find?
You will find the following types of radar PCBs:
Doppler Radar PCB
This radar PCB employs the Doppler Effect to determine the data velocity for an object with a specific distance.
You can do this by sending electromagnetic signals in the object’s direction.
Thereafter, you can examine how the object’s action impacts the frequency of the returned signal.
The adjustment allows for exact measurement of an object’s radial component of velocity in reference to the radar.
Microwave Doppler Radar PCB That Is Suitable To Use As Motion Sensor
Monopulse Radar PCB
This radar type contrasts the signal received using a certain radar pulse by comparing the signal’s characteristics as observed previously.
A conical scanning radar circuit is the most common type of monopulse radar.
The conical scanning radar circuit examines the results of two methods for directly measuring the object’s position.
Passive Radar PCB
Primary use of this radar PCB type is detection and pursuit of targets by processing information from ambient illumination.
Communication signals, as well as commercial broadcasts, are among these sources.
Passive Radar PCB
Weather Radar PCB
These employ radio signals with circular or horizontal polarization to detect wind direction and weather conditions.
You determine the frequency of a weather radar by a trade-off between attenuation and precipitation reflection resulting from atmospheric water steam.
The design of some of these radar types employs Doppler shifts to determine wind speed and dual-polarization for identifying rainfall type.
Pulsed Radar PCB
Pulsed radar PCB fires high-intensity, high-frequency pulses at the target object waits for the object’s echo signal before sending another pulse.
The pulse repetition frequency determines the radar circuit’s range and resolution employing the Doppler shift technique.
The Doppler shift technique detects moving objects since echo signals from static objects are in phase and thus cancel out. Contrarily, echo signals from moving objects have some phase differences.
What Are The Categories Of A Doppler Radar PCB?
You can find different categories of the Doppler radar PCB depending on the wavelengths they support. These are:
L Band Radar PCB
The operation wavelength of this type is 15-30 cm with a corresponding frequency between 1-2 GHz. You find these radar circuit types commonly employed for studies involving clear air turbulence.
S Band Radar PCBs
The operation wavelength of S band radar PCBs is 8-15 cm with frequency range of 2-4 GHz. These wavelength and frequency parameters make these radar PCBs difficult to attenuate and thus suitable for weather observation.
C Band Radar PCBs
The PCBs in C band radars permit an operation wavelength measuring 4-8 centimeters with frequency range of 4-8 GHz.
Attenuation is easily handled with this radar circuit find that finds common employment in television broadcasting.
X Band Radar PCBs
The operation wavelength for PCBs in X band radars is 2.5-4 cm and a frequency operation range of 8-12 GHz.
This circuit has increased sensitivity thanks to the reduced wavelength allowing detection of smaller particles.
You can employ this circuit to detect moisture presence allowing use in cloud research.
K Band Radar PCBs
The radar circuit of K band radars supports wavelength operation of .75-1.2 cm and also 1.7-2.5 cm.
Additionally, the frequency range is two-fold between 27-40 GHz and 12-18 GHz.
What Are The Materials You Use For Radar PCB?
You can employ the following PCB materials for your radar PCB:
You can have epoxy-based materials containing hydrocarbon resin matrix combined with woven glass and inorganic fillers. You find these materials allow use of a low profile copper film and a reduced oxidation process.
PTFE is a synthetic fluoropolymer that you can employ with inorganic fillers and woven glass for radar PCB fabrication.
You find this material common for single and double sided boards or multilayer boards with low layer counts.
What Is The Role Of Delay Line Cancellers In Radar PCBs?
The delay line canceller operates as a filter, removing the echo signals’ DC components obtained from stationary targets.
Consequently, you note that you can receive AC components from non-stationary objects’ echo signals.
You find delay line cancellers classified into two expressing their line count: single delay line canceller and double delay line canceller. The single delay line canceller combines one delay line alongside a subtractor.
The double delay line canceller cascades a line pairing making its output equal to the square of a single delay line’s output.
Diagrammatical Representation Of A Delay Line And How It Works
What Angular Tracking Techniques Can You Employ In A Radar PCB?
A radar PCB’s antenna pencil beams do angle tracking with antenna’s axis as the reference direction. If the goal and reference directions are dissimilar, angular error occurs, which is the two directions’ difference.
There are two angular tracking techniques you can employ:
Sequential lobing occurs when you alternately shift the antenna beams between two patterns for target tracking.
You can use this method to locate an angular inaccuracy in a single coordinate while specifying its size and direction.
You find sequential switching has the major advantage of providing a high level of accuracy in determining the target’s location.
Conical scanning occurs when the antenna beam rotates continuously to monitor a target before determining its position via conical scan modulation.
The squint angle forms between the rotation and the beam axes.
Modification of the echo signal from the target is at a frequency equal to the rotational frequency of the antenna beam.
You determine the modulated signal’s amplitude by the angle between the target’s direction and the axis of rotation.
The recovery of the conical scan modulation from the echo signal and later application to a servo control system is paramount.
As a result, this shifts the antenna beam axis towards the target direction.
What Are The Parameters Of A Radar PCB’s Antenna?
You find four major parameters of the radar PCB antenna as follows:
Directivity is the ratio of the subject antenna’s highest radiation intensity to that of an isotropic antenna radiating similar total power.
Despite the fact that a radar PCB’s antenna radiates power, the direction in which it radiates is extremely important.
The radar PCB antenna under investigation is the subject antenna whose radiation intensity direction specific while sending or receiving signals.
As a result, you consider the radar PCB antenna to have directivity in that direction.
Antenna Efficiency describes the ratio of the radar PCB antenna’s radiated power to that of the input power received by it.
For a given input, the antenna design intends for power radiation with reduced losses.
An antenna’s efficiency describes how well it can deliver its output with the least amount of losses in the transmission line. You can also refer to antenna efficiency as its Radiation Efficiency Factor.
The ratio of the effective radiating area to the actual area of the aperture determines a radar PCB antenna’s aperture efficiency.
A radar PCB antenna is a device that radiates energy through a hole.
The effectiveness of this radiation should be such that it causes least amount of losses.
You need to consider the physical area of the aperture as it influences the radiation’s effectiveness.
The antenna’s gain is the intensity of radiation’s ratio to that intensity obtainable by an accepted isotropically radiated power. You find the gain of an antenna considers the antenna’s directivity as well as its effective performance.
You can use the radiation intensity you acquire as a reference if the power accepted by the antenna was emitted isotropically. An isotropic emission is one that occurs in all directions.
What Antenna Types Can You Use In A Radar PCB?
A radar PCB antenna is a transducer that allows the board to communicate via electromagnetic waves through electrical conversion.
You find two common antenna types in radar PCBs: parabolic reflector antennas and lens antennas.
A Parabolic Reflector Antenna
Parabolic reflector antennas aid in achieving great directivity while maintaining a compact beam width.
Lens antennas consist of glass and employ a curved surface for both signal transmission and reception using converging and diverging properties.
Radar PCB With A Lens Antenna
What Advantages Can You Derive From Employing Radar PCB?
You find the following benefits in using the radar PCB:
- The signal emitted by a radar PCB can go through materials such as rubber and mediums like clouds allowing data collection.
- You can employ radar circuitry in determining an object’s position, distance and even velocity when it’s in motion.
- You do not require a particular medium to transmit radar signals from a radar PCB. You can transmit signals through air, water rand space without need of wire.
- A radar PCB can hold large data amounts since it can operate in high frequency.
- When using radar PCBs to transmit signals, you can cover a large geographical area without incurring extra cost.
What Display Types Can You Use With A Radar PCB?
A display is an electronic device that allows you to visually present data. You find many radar PCB displays are two dimensional with capability for both manual and remote tracking.
These display types are: A-scope, B-scope, C-scope, D-scope, E-scope, F-scope, G-scope, H-scope, I-scope, J-scope, K-scope, L-scope, M-scope, N-scope, O-scope, P-scope and R-scope.
A-scope employs the horizontal coordinate for range and the vertical coordinate for echo amplitude while allowing deflection modulation.
For the B-scope, the horizontal coordinate indicates the angle of azimuth while the vertical coordinate indicates the target range.
A Diagram Illustrating A, B and C- Scope Display Types
Why Is A Duplexer Necessary In A Radar PCB?
A duplexer is a microwave switch that connects the transmitter part to the antenna for signal transmission.
You need a duplexer if you want to use the same antenna for both signal transmission and reception in two-way communication.
When you transmitting a signal using a radar PCB with a duplexer, the radar cannot receive a signal at that time.
The duplexer also links the radar PCB’s antenna to the receiver area, allowing signal reception.
When receiving a signal, your radar PCB antenna cannot broadcast signals. Consequently, you find the duplexer isolates both the transmitter and receiver parts.
There are three types of duplexers based on configuration: Branch-type Duplexer, Balanced Duplexer and Circulator as Duplexer.
A Duplexer Used As A Receiver and Transmitter
What Are The Design Steps You Employ In Radar PCBs?
Fabrication of a radar PCB includes the following design processes:
Conceptualization allows you to determine your intended radar PCB use.
You can employ radar circuitry for different applications such as locating targets and, determining the speeds and distance of objects.
Additionally, you need to consider factors such as component population, operating temperature, required features and board size.
A schematic diagram includes information related to your radar PCB such as component details. Having a schematic diagram is also prudent in coming up with your bill of materials.
Creation Of Block Diagram
A block diagram for your radar PCB clearly describes your board indicating dimensions and board architecture.
Here, you illustrate the areas on the board for component attachment and those earmarked for other board features.
The manufacturing process entails the approach you intend to pursue in fabricating your radar circuit board.
When coming up with the manufacturing process, you consider factors such as, the material to use and stack up.
Component placement is a wide step in the design process that covers component-related factors such as density and positioning.
When positioning components, keep them close while ensuring the traces are not long.
Efficient component positioning ensures your radar circuit board is of good quality.
You also determine the order of attaching your components on the board where you can start with connectors.
Also consider the routing processes you’ll employ for your components and the circuit priority. Where you position your components influences the functionality of the radar PCB alongside performance effectiveness.
When you tightly space your components, you inhibit automation, testing and repair processes resulting in slow production.
Furthermore, you have to align your components in similar direction to improve manufacturability.
Circuit routing on a radar PCB covers the connection of components according to priority especially active components.
You begin with the most delicate circuitry on your radar PCB to prevent interference during installation of other board features.
What Aspects Do You Consider When Drilling Radar PCBs?
When drilling a radar circuit board, you find the following aspects essential:
The aspect ratio (AR) is a characteristic that determines your radar PCB’s reliability.
The aspect ratio of a through-hole radar PCB is the ratio of its thickness to that of the drilled hole’s diameter.
When it comes to microvias, it is the ratio between the hole depth and the drilled hole’s diameter.
The aspect ratio determines how well you can layout copper in the vias.
The drill-to-copper clearance is the distance between a drilled hole’s edge to the closest copper article.
Such a copper article can be a trace or copper pour which can cause major disruptions from a minor deviation.
What Factors Should You Consider When Selecting Surface Finish For Your Radar PCB?
A surface finish allows you to protect your copper features from oxygen-induced corrosion that is key in maintaining high board performance.
When you employ a surface finish, you secure your radar PCB’s circuitry with components.
There are several surface finishes available such as HASL, ENIG, OSP and Immersion Tin and Silver. When selecting a surface finish, you generally consider the following factors:
- Sensitivity during handling: Some surface finishes are highly sensitive to touch which can cause contaminating or even damage through breakage.
- Presence of lead: Lead is a hazardous substance and therefore its use on boards such as radar PCB is under restriction.
- Shelf life: The shelf life of a surface finish illustrates how long the finish can remain intact while in storage. A good surface finish can be kept in storage for six months or longer.
- Wire bonding ability: A surface finish should allow the formation of strong and reliable bonds with the board wires.
- Pitch tightness: when employing a surface finish on your radar PCB, it should be capable of supporting components with tight pitch.
- Compatibility with contacts: You need to consider whether your surface finish is compatible with different contact types on your radar PCB.
- Cost: Different surface finishes come at different costs depending on its properties. For basic radar PCBs, you do not need to break the bank on a surface finish.
Various Surface Finishes That You Can Select
Why Is ENEPIG A Good Surface Finish For Radar PCBs?
ENEPIG stands for Electroless Nickel Electroless Palladium and Immersion Gold.
You find this surface finish type intends to entirely prevent the formation of metallic compounds between layers of nickel and gold.
You observe this is possible by its incorporation of palladium which has high stability between the two metals.
The palladium layer effectively prevents nickel migration and the formation of new compounds, avoiding the black pad that happens in ENIG.
Other advantages you associate with ENEPIG include:
- ENEPIG bests other popular finishes such as ENIG, Lead Free-HASL, Immersion Silver and OSP in resistance to corrosion after-assembly.
- You also find the absence of lead in ENEPIG makes it a safe surface finish for radar circuit boards.
- The outcome of employing ENEPIG as a surface finish is a smooth and flat surface capable of multi-cycle assembly.
- ENEPIG forms good wire bonds and has impressive solderability quality.
- The resistance of ENEPIG to oxidation and heat is excellent.
- ENEPIG has a long shelf life that can exceed twelve months.
What Impedance Matching Methods Can You Use On A Radar PCB?
Impedance matching involves the peculiar design of load and source impedances to reduce the reflection of signal or power transfer optimization.
In this case, you need to have equal supply and load in the circuit.
There are two common impedance matching methods as follows:
Series Termination Matching
Sometimes the signal source’s impedance is less than the transmission line’s characteristic impedance.
You employ a resistor in series between the source of signal and line of transmission.
This causes the source’s output impedance to match the transmission line’s characteristic impedance.
Consequently, the load’s reflected signal reflected becomes suppressed.
You find this kind of impedance matching ensures low power consumption with no extra DC load on the driver.
Furthermore, instead of additional signal-ground impedance you only have a resistive element.
Parallel Terminal Matching
When the signal source’s impedance is very low, you can match the load’s input impedance to the transmission line’s characteristic impedance.
This is possible by boosting the parallel resistance to remove load end reflection.
You can implement parallel terminal matching in two ways: single resistance and double resistance.
The main advantage of parallel terminal matching is its basic approach and straightforward implementation.
How Much Does A Radar PCB Cost?
There are many radar PCBs available employable in different applications such as hand receivers and in satellites for communication.
You find the cost of the radar PCB is dependent on its complexity and factors such as density and performance levels.
A basic radar PCB with a single configuration such as transmission only can cost less than five dollars.
However, you can find radar PCBs costing up to hundreds of dollars such as high performance ones with dual functionality.
