What is the Function of Automotive Radar?
1 Answers
Automotive radar, as the name suggests, is radar used for automobiles or other ground motor vehicles. Therefore, it includes various types of radar based on different technologies (such as laser, ultrasonic, and microwave), with different functions (such as obstacle detection, collision prediction, adaptive cruise control), and employing different working principles (such as pulse radar, FMCW radar, and microwave impact radar). Microwave radar holds significant commercial importance in automotive radar. Below is a detailed introduction to automotive radar: 1. Speed Measurement Radar: It can measure the speed of the vehicle by detecting the rotation speed of the wheels. 2. Obstacle Detection Radar: This type of radar can observe the terrain in conditions of low or no visibility and alert the driver to prevent accidents. 3. Adaptive Cruise Control Radar: It can adapt to the surrounding environment of the vehicle and maintain a safe speed based on the speed of the vehicle and the one ahead. 4. Collision Avoidance Radar: This radar can measure potential hazardous obstacles on the road ahead that may cause a collision based on the vehicle's current direction and speed. It is suitable for situations with low atmospheric visibility and poor judgment (such as too short a distance or too high a speed). The purpose is to warn the driver to deploy airbags or other braking devices and control the vehicle's speed.
