For the conventional radar target clutter detection technology,the background power level estimation of each azimuth-distance unit is obtained by the recursive update of the continuous scanning period samples in the resolving unit,but this estimation method fails when there are a large number of interfering target samples in the continuous scanning period samples of the resolving unit.In response to this,this paper draws on the sample screening technology in the spatial constant false alarm to the time domain constant false alarm,and proposes an OTSU-CCA-based clutter detector to improve the accuracy of background power level estimation by eliminating the potential interference target samples in the continuous scanning period samples,thereby enhancing the detection performance of clutter map.
