Abstract

In order to solve the problem that the detection performance of the radar target detector decreases badly in non-homogeneous environments. Based on the actual echo clutter distribution, a Multiple Switching CFAR detector (MS-CFAR) is proposed. Firstly, the maximum reference units in the left and right reference sub windows are removed by censoring threshold. Then, compare the number of remaining reference cells in the left and right reference windows and variation index with the corresponding threshold respectively, and select the appropriate reference cells to accurately estimate the background noise power. Compared with the simulation and analysis results of other detectors, the proposed detector had the best detection performance and stability in multi-interfering targets, clutter edge and other non-homogenous environments. The results show that the proposed detector still has a good detection performance in non-homogeneous environments.
