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。
The target of the quasi-optical zone scatters the high-resolution detection signal and shows multiple scattering centers. In this paper, we use the physical properties of the target to derive the approximate proportional relationship between the scattering signals of two adjacent azimuths. The Merlin transform is used to reconstruct the target model, which effectively overcomes the sensitivity of the target scattering center model to the observed azimuth Changes in the characteristics of the selection of the difficulties. In this paper, three kinds of aircraft targets (J-7, B52, Mig27) were identified experimentally, and the results show that the proposed method is effective and feasible.
