Title:
LASER RADAR, AND ANTI-JAMMING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/233415
Kind Code:
A1
Abstract:
A laser radar, and an anti-jamming method therefor, comprising: modulating emission time of a laser radar by injecting random timing jitter in an time interval of an emission time series (102); enabling the laser radar device to emit a laser pulse according to the modulated emission time (104); obtaining receiving times of echoes received by the laser radar, the echoes comprising an expected echo of the present laser radar and an unexpected echo, and the unexpected echo comprising an echo of other laser radar caused by crosstalk of the other laser radar (106); and identifying and removing an interference echo according to the emission time of the present laser radar device and the receiving times of the echoes received by the present laser radar device and according to the correlation. For crosstalk caused by multiple laser radars being used in a same scene, the method can combat the crosstalk to a certain extent.
