Functional introduction of Radar PCB

Radar PCB is a circuit board specialized in radar systems for connecting and supporting various electronic components and devices in the radar system. It plays a key role in the radar system and enables the normal operation and efficient performance of the radar system.

The main roles of the radar PCB include:

1. providing support and connection of electronic components: the radar PCB is arranged with a variety of electronic components, such as integrated circuits, capacitors, inductors, etc., and is able to provide support and connection of these components so that they can work properly.

2. Realize signal processing and data transmission: the circuitry on the radar PCB can process and analyze the received radar signals, extract useful information, and transmit the data to other parts for further processing.

3. realize power amplification: radar system needs to amplify the signal to enhance the signal strength and distance detection ability. The power amplification circuit on the radar PCB can realize this function.

4. RF signal processing: radar system RF signals need to be processed and adjusted to meet the needs of different radar applications. The RF circuit on the radar PCB can realize this function.

The Fundamental Parts Of A Radar PCB

The essential parts of a radar PCB include:

Transmitter: A signal from the waveform generator is not strong enough for radar. Therefore, the purpose of a transmitter is to amplify the signal using a power amplifier.
Receiver: A receiver detects and processes the reflected signal using a receiver processor, like the super-heterodyne.
Antenna: Contains parabolic reflectors, planar arrays, or electronically steered phased arrays. It is responsible for sending out and receiving the pulses.
Duplexer: A duplexer is a device that enables the antenna to do the tasks of a transmitter and receiver.
Waveguides: Waveguides are the transmission lines for transmitting radar signals.
Threshold Decision: This part compares the output from the receiver to the threshold to determine the presence of an object. After comparison, if the work falls below the point, you assume noise exists.

Functions of the radar circuit board in detail

1. signal processing function: the signal processing circuit on the radar circuit board can filter, amplify, modulate and other processing of the received radar signals to extract useful information and remove noise and interference.

2. data transmission function: the data transmission circuit on the radar circuit board can transmit the processed radar data to other parts for further processing and analysis, such as monitors, computers and so on.

3. power amplification function: the power amplification circuit on the radar circuit board can amplify the radar signal to enhance the signal strength and distance detection ability.

4. RF signal processing function: the RF circuit on the radar circuit board can process and adjust the RF signal in the radar system to meet the needs of different radar applications.

Types Of Radar PCB

There are five types of radar PCBs. They include:

Doppler Radar PCB

As the name suggests, this type uses the Doppler effect to determine the data speed for objects within a specific distance.

It sends electromagnetic signals to the object and then measures how the target affects the echo’s signal frequency.

It is possible to determine an object’s velocity with the radar as the reference for the measurement and adjustment.

Monopulse Radar PCB

Monopulse radar PCBs contrast the received signal using a specific pulse by comparing the signal’s characteristics as previously observed.

The most common type is the conical scanning radar circuit. It checks the results of the two methods to measure the object’s position directly.

Passive Radar PCB

A passive radar PCB is a detection device that processes ambient illumination information. After that, it assists in pursuing targets.

Weather Radar PCB

Wind and weather detection is critical in today’s world, and weather radar PCBs help with that by using radio frequency signals. However, there is a tradeoff between precipitation reflection due to atmospheric moisture and attenuation.

Similarly, you can use a weather radar that features Doppler shifts to measure wind speed and dual-polarization for determining the type of rainfall.

Pulsed Radar PCB

Lastly, this PCB type shoots high-frequency, high-intensity pulses at the target, then waits for the bounce-back signal before firing again.

To clarify, using the Doppler shift technique, the repetitive firing frequency determines the radar PCB’s range and resolution. This technique senses moving objects from the echoed signal in the following manner:

When bounced back, signals from static objects are in phase and cancel out.
When Pulses from moving objects have phase differences.

Application of radar circuit boards in different types of radar systems

1. Military radar: radar circuit boards play a vital role in military radar systems. It can realize high-precision target detection and tracking, as well as enemy identification and other functions, providing important support for military operations.

2. Civilian radar: radar circuit boards are widely used in civilian radar systems, such as weather radar, aviation radar, marine radar and so on. It can realize the weather forecast, aviation navigation, marine resources survey and other functions, to provide important services for the people’s life and social development.

3. Automotive radar: the radar circuit board plays a key role in the automotive radar system. It can realize the functions of obstacle detection, automatic driving, intelligent cruise and other functions of vehicles, and improve driving safety and driving comfort.

Advantages of Radar PCBs

Radar PCB signals can penetrate clouds and materials like rubber.
The radar PCB circuitry can determine an object’s velocity, distance, and position when in motion.
Signals/pulses from a radar PCB don’t need a medium (wire) for transmission because they can travel through space, water, and air.
The PCB operates at a high frequency to hold large amounts of data.
Signals from a radar PCB can cover large areas without requiring extra costs.
