Target deteciton algorithm for spatial diversity MIMO radar with space partition

For spatial diversity multiple input multiple output (MIMO) radar, target echo signals received by its widely separated antennas may be semi-correlated and different in SNR. According to the correlation and SNRs of received target echo signals, a space partition based target detection method is proposed, which partition the surveillance volume into two sections, one using the coherent accumulating detector and the other using the incoherent accumulating detector. The partition method is shown to achieve an improved detection performance at a low computation cost.
