New detection algorithm for range spread target via statistical property diversity

Based on the statistical property diversity of target and disturbance, a new detection algorithm for range spread target is proposed in this paper. To this end, we first resort to secondary data set to obtain the statistic property of clutter of the cells under test. Then two detectors which focus on calculating the statistical difference of clutter and target plus clutter are designed. Their performance assessment and the comparison with a previously proposed detector show that the proposed detectors can be a viable means to cope with uncertain detection environments.
