论空载雷达天线的再辐射及抑制

On the Re-radiation from Airborne Radar Antenna and Its Suppression

本文论述了空载雷达天线由于极化失配、照射失配和阻抗失配产生的再辐射。根据几何光学理论,利用孔径场法进行了分析。较详细地给出了抑制再辐射和RCS减缩的技术途径。

This paper deals with the re-radiation from airborne radar antenna due to polarization, illumination and impedance mismaching. Based on geometrical optics theory, the re-radiation is analysed by using aperture field method. Techniques for re-radiation suppression and radar cross section reduction are also presented in details.
