摘要：

阐述了猫眼效应的基本原理,给出了离焦时的猫眼模型,采用光线追迹的方法着重分析了离焦时猫眼系统的回波功率的变化情况。通过分析可看出,后向移动光敏面的可调制范围远远大于前向移动光敏面的可调制范围,这使得应用猫眼系统后向离焦量的改变,来改变回波功率的大小,使其能传递信息成为可能。

Abstract: This paper introduced the basic principle of the "cat-eye effect" in detail.A basic model of "cat-eye effect" has been given when the plane of reflect deviates from focus plane.On emphases,the intensity changes of the reflected wave when the planet deviated from focus plane with the "ray tracing" method.The properties of the focus-deviations in the "cat-eye" systems were carefully studied.It is possible to employ this decreasing curve to the transfer of the information.
