Abstract

The radar scanning system disclosed by the invention comprises a target identification module, a target tracking module, a scanning decision module and a scanning control module, the target identification module is used for identifying characteristic information of positions, speeds and accelerations contained in all to-be-scanned targets in a radar scanning area; the target tracking module is used for tracking the to-be-scanned targets in the radar scanning area identified by the target identification module to obtain target trajectory information; the scanning decision module distinguishes an interested target from an uninterested target according to the target characteristic information and the target trajectory information of the targets in the radar scanning area, formulates a differentiated scanning strategy and sends the differentiated scanning strategy to the scanning control module; and the scanning control module performs scanning according to the differentiated scanning strategy of the scanning decision module. According to the radar scanning system provided by the invention, the scanning density of other positions is reduced by performing encrypted scanning on a sensitive target, so that the radar scanning accuracy and timeliness are improved, and the requirements of an automatic driving technology of a motor vehicle are met; the invention further discloses a radar.

Description

technical field [0001] The invention relates to a radar scanning system for scanning the surrounding environment and its radar. Background technique [0002] Radar is generally installed on motor vehicles. By scanning the objects in the surrounding environment of the motor vehicle, the radar can reduce the collision between the motor vehicle and the surrounding objects. With the gradual application of the automatic driving technology of motor vehicles, there are higher requirements for the accuracy and timeliness of the scanning information provided by the radar, and the accuracy and timeliness of the scanning information provided by the radar have a great impact on the safety of the automatic driving of motor vehicles. Impact matters. [0003] In the current prior art, radar scans are performed in a fixed period. As disclosed in Chinese patent document CN110402399, the light intensity is changed, or the center line of the scanning area of ​​the laser radar is changed as d...
