摘　　要：研究目标冲击响应P特征检测算法 (PFD) .首先介绍如何由冲击雷达所获得的观测中求取目标的冲击响应 ;然后以目标冲击响应为模型以SVD技术为主要手段提出了一种具有良好效果的模型判阶方法 ;建立了以模型阶为判决统计量的P特征检测算法 ,并进行仿真实验 ,获得了满意的结果 .Target P feature detection algorithm of impulse response is studied in this paper, which starts with an introduction of how to get impulse response of target from impulse radar;followed by the presentation of an effective method of deciding order about model based on SVD technical and model of impulse response. Finally, P feature detection algorithm based on model order's statistics is established. Theoretical analysis and simulation results show that this algorithm is of good detection performance.
