| 摘 要： | 准光学区目标对高分辨探测信号的散射，表现出多散射中心。本文利用目标的这一物理特性，推导了相邻两个观测方位角上散射信号的近似比例关系，采用梅林变换重建了目标类模式，有效地克服了目标散射中心模型的参数敏感于观测方位角变化而带来的特征选择的困难。文中针对三种飞机目标（歼七、Ｂ５２、Ｍｉｇ２７）进行了识别实验研究，结果表明了本文所提出的目标识别方法是有效可行的。

| Abstract: | Based on the concept of scattering center and applying approximation scale re- lationship of back scattering signals in two near aspect angles,this paper adopts Mellin transform to reconstruct target's pattern and to overcome effectively problems of features extraction caused by the factor that scattering centers arc sensitive to the changes of aspect angles.By using three cale aircraft targets(Q7,B52 and Mig27),the recognition experimental study has been done. The results show that the method presented in the paper is effective and feasible. |
