Abstract

Abstract

A detector based on order statistic for range spread target in white Gaussian noise is derived in this paper. With the fact that the power of wideband radar target return is concentrated in several range bins, the data in the detection window is re-arranged in the order of energy decreasing, then the energy accumulation and detection is implemented in order, until the decision is made. The false alarm rate of the detector is derived and the method of threshold setting is proposed. Finally, the performance of proposed detector compared with that of the integration detector is given by Monte Carlo experiment, with two special energy distributing range profiles and a measured range profile of an actual target. For the range profiles that the energy of the return is concentrated in several range bins, the detector proposed in this paper has a better performance than the integration detector.
