Title:
DISTANCE AND SPEED DETERMINATION METHOD AND APPARATUS FOR LIDAR
Document Type and Number:
WIPO Patent Application WO/2023/193420
Kind Code:
A1
Abstract:
A distance and speed determination method and apparatus for a LiDAR. The method comprises: measuring a rising interval beat frequency signal, a constant frequency interval beat frequency signal and a falling interval beat frequency signal between a transmitting signal and an echo signal (S201); and determining the speed and distance of a target object relative to the LiDAR according to the rising interval beat frequency signal, the constant frequency interval beat frequency signal and the falling interval beat frequency signal (S202).
