Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser detection, and in particular to a laser radar device. Background technique [0002] The laser radar device transmits a detection signal (laser beam) to the target, and then compares the received signal (target echo) reflected from the target with the transmitted signal, and after appropriate processing, the relevant information of the target can be obtained. The radar device can accurately measure the position, motion state and shape of the target, detect, identify, distinguish and track the target. Because of its advantages of fast measurement speed, high precision and long range, it has been widely used in smart cars and other fields. [0003] Since vehicle-mounted radar usually needs to monitor road condition information in real time, and adapt and work in various environments, it needs strong hardware and firmware support, resulting in increased power consumption of heating...
