Abstract
This study investigates the problem of the multiple moving target detection using multistatic radar system (MSRS). A detector based on generalized likelihood ratio test (GLRT) is presented with unknown target location and velocity. A lack of information about accurate target location will cause an error in registration. Some spatial resolution cells of no targets gather observation data of targets, which leads to extra false alarm, called “ghost target”. Therefore, “ghost target” is discriminated and the interferential amplitude is estimated by maximum likelihood estimation (MLE). Subsequently, the GLRT detector is modified to reduce the false alarm and detect target. Simulation results show that the proposed algorithm can suppress the interference while accurately detecting multiple moving targets.
