Abstract

The present invention relates to the technical field of radars and discloses a laser radar system based on MEMS micro mirror scanning. The laser scanning of a target area is carried out by using the outgoing laser emitted by an MEMS micro mirror reflection laser according to a preset specified rotation angle, a receiving detector receives the reflection laser of a target reflection object in a target area and converts the reflection laser into an echo pulse signal, and a signal processing module receives and processes the echo pulse signal so as to obtain the position information of the target reflection object. Therefore, the laser radar system has a high measurement frequency and low cost.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a laser radar system based on MEMS micromirror scanning. Background technique [0002] The current multi-line laser radar realizes multi-line scanning by multiple transmitting lasers and multiple receiving detectors, such as the laser radar VLP-16 of Verlodyne Company in the United States, which requires 16 lasers to transmit and receive, 16 transmitting circuits and receiving circuits. It is difficult to deal with, the timing algorithm is difficult to control, and this laser uses a laser diode, the maximum peak power of the laser is 75W, and when the measurement distance is 200m, if the target reflectivity is small, there will be no echo signal. [0003] In summary, there are obviously inconveniences and defects in the actual use of the prior art, so it is necessary to improve it. Contents of the invention [0004] In view of the above-mentioned defects, the object of the prese...
