Information

The most basic working principle of lidar sensor is the same as that of radio radar, that is, a signal is sent by the radar transmitting system, hitting trees, roads, bridges and buildings on the ground, causing scattering, and being reflected by the target and collected by the receiving system. The lidar sensor The distance to the target is determined by measuring the running time of the reflected light.

As for the radial velocity of the target, it can be determined by the Doppler frequency shift of the reflected light, or it can be measured by measuring two or more distances and calculating the rate of change to obtain the velocity. This is also the basic working principle of direct detection radars. .
The function of lidar sensor is to accurately measure the position (distance and angle), shape (size) and state (speed, posture) of the target, so as to achieve the purpose of detecting, identifying and tracking the target.
The lidar sensor is a radar system and an active sensor. The data formed is in the form of a point cloud. The lidar sensor's working spectrum is between infrared and ultraviolet, and it is mainly composed of transmitter, receiver, measurement control and power supply.
