Document Type and Number:
WIPO Patent Application WO/2023/071888
Kind Code:
A1
Abstract:
A radar speed measurement method, a radar, a radar speed measurement device, a server, and a storage medium. The method comprises: acquiring a measurement parameter set between a radar and a target to be measured (S11); according to the measurement parameter set, determining position information of said target relative to the radar (S12); by means of radar measurement, obtaining the relative movement speed of said target along the beam line-of-sight direction of the radar (S13); and, according to the relative movement speed and the position information, determining the absolute movement speed of said target along the direction of movement thereof (S14). By means of calculating relative position information of a target to be measured, the problem of speed conversion under a three-dimensional model is solved and the speed of the target along the actual driving direction at any height and any pitch in a three-dimensional space is accurately measured, thereby facilitating law enforcement departments determining and tracking violations.
