Abstract

The invention discloses a target tracking method and device for a radar and a storage medium, and the method comprises the steps: determining a non-filtering region meeting a preset condition in a current detection region of the radar according to the position information of the radar and / or the motion state information of at least one target detected by the radar in a preset time period, determining the area except the non-filtering area in the detection area as a filtering area; aiming at the detection point of the current frame of the radar, filtering the detection point with the Doppler velocity of zero in the filtering area; and performing motion state updating on the stably tracked target according to a filtering result. According to the technical scheme provided by the invention, the technical problem in the prior art that the track is interrupted or the track is not tracked in time after the detection point with the Doppler velocity being zero is filtered when the moving target enters the radar detection area in the process of tracking the target by the radar can be solved.

Description

technical field [0001] The present invention relates to the technical field of radar, and in particular, to a target tracking method, device and storage medium for radar. Background technique [0002] In an intelligent transportation system, sensors are required to collect traffic data to ensure the smooth operation of traffic. When detecting targets, millimeter-wave radar can distinguish the speed, number and direction of moving targets through pulse signals, and is not affected by light and weather. Wave radars can be used to monitor road traffic and play an irreplaceable role in the data collection of traffic systems. [0003] When the target is tracked by the millimeter wave radar, it needs to be detected based on the detection points generated by different objects. The radar transmits pulse signals to all objects in the detection area, obtains the echo signals reflected from multiple detection points on different objects, and calculates the Doppler velocity of the obje...
