Description

Buried laser radar device

Technical Field

The utility model relates to a bury formula laser radar device belongs to laser radar technical field.

Background

A laser radar (LiDAR) is a radar system that detects characteristic quantities such as a position, a velocity, And the like of an object by emitting a laser beam. The working principle is that a detection signal (laser beam) is transmitted to a target, then a received signal (target echo) reflected from the target is compared with the transmitted signal, and after appropriate processing, the relevant information of the target can be obtained; such as: target distance, orientation, altitude, speed, attitude, and even shape. The laser receiver converts the light pulse reflected from the target into the electric pulse.

Laser radars produced on the market at present are various in types and application scenes, but the laser radars are fixedly installed; in order to solve the problem of installation and fixation of the laser radar, various laser radar fixing devices are also available in the market, but most of the laser radar fixing devices are designed for vehicles, ships, airplanes and other vehicles; lidar directed to ground installations is rare.
