Radar track initiation method based on adaptive gate

The invention provides a radar track initiation method based on a self-adaptive gate. The method comprises the following steps: acquiring a radar plot data set of an initial scanning period; converting the obtained distance and radial speed of the trace point into distance and speed under Cartesian coordinates; generating a temporary track set; carrying out self-adaptive gate constraint matching on trace points in other period data sets and all the tracks in the temporary track set; judging the number of trace points in the gate, screening the trace points, and updating the quality of the track; and judging the track quality, determining the track type according to the quality score, and starting or revoking the track. According to the method, the multi-dimensional measurement information is used for carrying out track matching, and the size of the adaptive gate is set according to the track quality score, so that the problems that the track initiation efficiency is low and the target tracking performance is
