Automotive radar PCBs are one of the key components in automotive electronic systems. They are used to support a variety of radar systems, which play a vital role in the vehicle's advanced driver assistance systems (ADAS) and autonomous driving technologies. Here are some important information about automotive radar PCBs.
Functions and Applications
1) Collision Avoidance System
The automotive radar PCBs are mainly responsible for receiving, processing and analyzing radar signals, realizing the detection of all possible obstacles or vehicles in front of the vehicle, and providing corresponding warnings or triggering automatic braking functions.
2) Blind Spot Detection
The blind spot detection function is responsible for a PCB-driven radar system, which can monitor the blind spot areas on both sides of the vehicle. When a vehicle enters these blind spots, the system will promptly issue an alarm to help the driver avoid potential collision hazards.
3) Adaptive Cruise Control (ACC)
Adaptive cruise control(ACC) is an advanced driver assistance systems, which is mainly composed of radar PCB and other components. The radar PCBs can help the vehicle maintain a safe distance from the vehicle ahead and automatically adjust the vehicle’s speed according to traffic conditions, thereby improving driving safety and comfort.
4) Lane Keeping Assistance
With the help of lane marking detection technology, the automotive radar PCBs can effectively help the vehicle always ensure that it is driving in the center of the lane.
Types:
1) Millimeter Wave Radar
The common frequencies are 24GHz or 77GHz, which have the characteristics of high resolution and long detection distance, and are widely used in front radar and side radar of the vehicles.
2) Ultrasonic Radar
It is mainly used for close-range detection, such as parking assistance and collision avoidance in low-speed environments.
Requirements:
1) High Frequency Performance
Radar PCBs need support high-frequency signal transmission, so specific high-frequency materials are usually used to reduce signal loss and interference, such as PTFE, ceramic filling materials, etc.
2) Multi-layer Structure
To accommodate complex circuit and antenna designs, automotive radar PCBs are usually multi-layer PCB.
3) High Reliability and Durability
The environment in which cars located is harsh, so automotive radar PCBs need to have properties such as high-temperature resistance, moisture resistance, and vibration resistance.
4) Miniaturization
To achieve optimal performance within the limited space inside vehicles, automotive radar PCBs need to be as small and lightweight as possible.
Market Trends
1) With the development of autonomous driving technology, the demand for high-performance radar systems continues to increase, which has promoted the advancement of radar PCB technology.
2) In the future, automotive radar systems will be more integrated, and multiple sensors and processing units may be integrated on the same automotive radar PCB, further improving system performance and reliability.
