Abstract

Laser radar is a radar system that uses laser as light source and works in the optical band. It is the product of the combination of laser technology and radar technology. It has the advantages of all-weather, high precision, anti-interference and miniaturization. Aiming at the great potential of laser radar, a laser radar system based on phase high-precision ranging is proposed. And aiming at the stability of output power caused by temperature variation of semiconductor laser, proposed a laser radar voltage matching algorithm based on machine learning. Through the experiment simulation and functional test, it is proved that the detection distance of the proposed laser beam can reach 300m with 0.1% precision, and it can greatly reduce the influence of temperature change on ranging, and significantly improve the ranging accuracy.
