moving target detection in mimo radar with widely separated antenna in α-stable clutter based on rao test

in this paper, the detector of moving target in mimo radar with widely separated antenna in the presence of α-stable clutter is proposed. due to the complexity of unknown parameter estimation in the presence of target, the rao test is applied. the α-stable model is a general model that can applied to different environments with appropriate selection of parameters. the problem with this model is that inexistence of closed form for the probability density function of the distribution. fortunately, there are models that approximate this distribution by closed form expression. in present paper, mixing of gaussian and cauchy model is used for expressing clutter. finally, the performance of proposed detector compared with optimal gaussian detector with a graph of the probability of detection versus signal-to-clutter ratio. the results of the simulation show that the performance of the proposed detector is far better than optimal gaussian detector.
