[0002] An automotive radar controller is an electronic device that uses radio waves to detect targets and determine the spatial position of a vehicle. Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and altitude. Automotive radar controllers are used for radar in automobiles or other ground motor vehicles. Therefore, they include various radars based on different technologies (such as laser, ultrasonic, and microwave) and have different functions (such as obstacle detection, collision prediction, and adaptive cruise control).

[0003] Currently, there is an automotive radar controller housing that includes an outer shell body. The four corners of the outer shell body are provided with docking corner posts. The outer shell body is provided with circuit board limiting posts and multiple support posts.
