摘要
抛物面天线目标在太赫兹波段下属于电大尺寸。基于电磁散射计算软件CST Micro-wave Studio来建立旋转对称抛物面天线目标的CAD模型,采用高频渐进法分别求解目标在太赫兹波段和X波段下的雷达散射截面,进而研究分析目标RCS特性,高分辨率一维距离像和逆合成孔径雷达像特性。
In terahertz regime, the parabolic reflector antenna （ PRA ） targets are electrically very large targets. The CAD model of the PRA was simulated with the electromagnetic scattering computation software CST Microwave Studio. The radar cross section（RCS） of PRA was solved by the high frequency asymptotic solver in X waveband and terahertz regime. The RCS characteristics, high range resolution profiles and inverse synthetic aperture image of the target are researched and analyzed.
