Radar plot condensation method and system and storage medium

The invention provides a radar plot condensation method and system and a storage medium. The method comprises the steps of: firstly performing singular value decomposition on the point trace data of each frame of the radar; according to the eigenvalue, selecting the data which is smaller than the original data but can express the original data to the maximum extent; clustering the obtained data bya DBSCAN algorithm, wherein the point traces formed in each cluster are considered to be splitting points of the same target; calculating the distance and azimuth ranges of each cluster, and dividingthe obtained ranges. According to the amplitude statistics, the dispersion coefficients of point traces in each interval are calculated, and the interval with small dispersion coefficients is taken as the condensation interval, and the average distance and azimuth of the interval are calculated, so that the point trace condensation is completed. The method of the invention realizes the point trace extraction by extracting
