Abstract
The problem of fluctuating signal detection in a background of spatially correlated interferences for MIMO radars with colocated antennas is considered. Optimum (LRT) algorithms are analyzed. A system of narrow receiving beams in MIMO radars without space scanning realizes preliminary spatial filtration: separation of targets and sidelobe interference sources. As a result, the complicated optimal detection algorithms with interference cancellation may be replaced by the simpler suboptimal algorithm. Comparative analysis of the optimal and suboptimal detection algorithms presented in the paper shows insignificant energy loss for the latter one.
