Abstract :
Phase synchronization errors (PSEs) are practically inevitable for non-coherent MIMO radar with widely separated antennas, so in this paper a two-step generalized likelihood ratio test (2s-GLRT) algorithm to target detection under PSEs. The expectation-maximization (EM) algorithm and detection criterion are employed to estimate the channel parameter and acquire target detector respectively. Simulation results verify the correctness of algorithm.
