Abstract

The embodiment of the invention discloses an anti-interference method for a laser radar and the anti-interference laser radar. The anti-interference method includes the steps that a transmitting control unit generates emitting laser information in each transmitting period according to a transmitting code word table; a laser transmitter transmits emitting laser light periodically according to the emitting laser information; a laser receiver receives reflected laser light, wherein the reflected laser light is the laser light after the emitting laser light is reflected by a measured object; a processor obtains effective laser pulses in the reflected laser light and discards interfering laser pulses according to the transmitting code word table. According to the embodiment, interference can beeffectively eliminated, and the safety performance and accuracy of the laser radar are improved.

Description

technical field [0001] The invention relates to the detection field, in particular to a laser radar anti-jamming method and an anti-jamming laser radar. Background technique [0002] Lidar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of the target. Its working principle is to first transmit the detection laser beam to the target, and then compare the received signal reflected from the target with the transmitted signal. After proper processing, the relevant information of the target can be obtained, such as target distance, azimuth, height, speed, attitude, and even shape and other parameters. [0003] Because of its excellent characteristics, lidar ranging plays an indispensable role in the perception link in the field of autonomous driving. However, as the use of lidar becomes more and more widespread, for any lidar, it will inevitably face the interference of lasers emitted by other lidars within its effective...
