摘　　要：本文对“猫眼”效应的研究进展作了综述,介绍了目前存在的几种“猫眼”效应模型,并推导出由于光敏面的离焦引起的发散角。对“猫眼”回波功率和漫反射小目标回波功率之比的物理意义作了解释。最后对“猫眼”效应应用中的一些问题作了讨论。In this paper the advances in the cat＇s eye effect are reviewed. Some models of the cat＇s eye retro - reflectors are given, and the divergence angle resulting from the position deflation of the focus of the photosensitive surface is derived. The ratio of the echo power of cat＇ s eye to that of the small diffuser is interpreted physically. Finally, some problems of the cat＇s eye effect in application are discussed.
