A New Approach to Range Spread Target Detection Based on Information Entropy
Based on the diversity between the information entropy of target echo and disturbance introduced by high resolution radar,a new detection algorithm for range spread target via Renyis entropy is proposed for the first time in this paper. The proposed entropy detectors performance assessment and its comparison with two previously traditional detectors show that the entropy detector can achieve satisfactory performance for the range spread target detection.Remarkably,the proposed entropy detector is not needed to estimate the parameters of clutter environment and is robust to the cells number of range spread target.
