As is a common concept in the working principle of radar systems, radar emits electromagnetic waves that propagate in the form of pulses. Therefore, if these waves collide with any object, they will reflect back to the device, thereby determining its size, position, and content. Therefore, we found that PCB is the driving core of these systems and ensured their performance and effectiveness.

The radar PCB consists of six basic components:

Sender: including the signal to be sent.

Receiver: Receive and process signals.

Antenna: Send and receive through PCB transmission and reception devices.

Duplex: It helps to enable the antenna to complete the tasks of transmission and reception.

Waveguide: a wave that carries the propagation of signals.

Threshold determination: It compares and identifies the things to be explored and identified.

Due to the crucial role that radar PCBs play in the performance of many high-frequency electronic systems and general radar systems, they possess many characteristics that result in a high demand for radar printed circuit boards in the PCB industry market, as follows.

The radar PCB provides support and connections for all components and electronic circuits integrated into the PCB.

It has high linear density and light weight. It is also designed with a thin thickness to ensure its high performance. Due to its light weight, small size, and effective performance, we have found that it is used in many electronic devices.

To achieve complete reliability in the analysis, processing, and transmission of low-noise, high stability signals, thereby providing and meeting the needs and requirements of many complex radar systems.

RF signal processing is performed through an RF circuit integrated with the printed circuit board used in the radar.

The radar PCB is designed with materials that have good electrical, mechanical strength, and impedance characteristics to ensure continuous performance and reliability.

As we mentioned earlier, radar PCB is the fundamental component of many radar systems and can be used for various types of applications, as it has several common types, including

Radar PCB is considered one of the most essential elements in the design of any high-frequency electronic device or radar system. We will mention some of these applications.

1. Applications in the military field

Radar PCB ensures the safety and accuracy of military operations, whether guiding missiles or identifying island, land, or sea targets. They also contribute to military surveillance and target tracking systems.

2. Civil application

The radar PCB can be used in a variety of civil service systems, such as monitoring and controlling traffic flow and adjusting aircraft movement in air navigation. We also found them in autonomous driving applications and advanced driver assistance systems (ADAS).

3. Space applications

Radar printed circuit boards help monitor planets and facilitate the smooth operation and transportation of spacecraft.

4. Security

Radar PCBs can be used for various alarm devices to prevent theft and fires, and also contribute to advanced sensor technology such as opening doors, turning on home lighting, etc.

Radar sensor PCBs also play a very important role in all safety sensor applications. The radar sensor PCB is highly sensitive to any unidentified movements or changes, such as temperature fluctuations. Due to their high sensitivity, PCB radar sensors can be used to detect the specific location of objects. This sensitivity is usually necessary in the field of safety to ensure that preventive measures are taken before a danger occurs.

Usually, the design process of radar PCB depends entirely on the system that will use the board. Therefore, the design process of the radar circuit board is based on the application. Sometimes we find layers that require high frequency and therefore high power, while other layers require low frequency and lower power. If the design is not carried out according to the requirements, it will not guarantee the required transmission speed and accurate data processing, thus reducing reliability.

We will mention some design steps to ensure the integrity of the radar PCB design, as shown below.

1. Create the circuit diagram included in the radar PCB board, indicating all the details required for the correct design of the circuit board and the necessary components in the printed circuit board.

Typically, radar PCBs contain many circuits that perform specific tasks, such as RF circuits designed for analyzing and processing radio signals, transmitter and receiver circuits, and other components. Design diagrams must be created for each circuit to estimate the number of components.

When designing an appropriate antenna to perform panel functional tasks, design factors such as antenna gain, direction, and frequency response should be considered.

4. Due to the sensitivity of radar PCBs to minor interference, performance requirements must be considered during the design phase, including radar response, mechanical performance, noise response, etc.

After drawing and planning the radar PCB board, we select appropriate materials for design in order to choose necessary materials with high characteristics, such as resistance to different climatic conditions (such as humidity, high and low temperatures) and corrosion resistance. Epoxy resin and polytetrafluoroethylene are commonly used in PCB manufacturing for radar applications.
