摘　　要：针对建立雷达目标动态多极化回波模型问题,提出了一种基于FEKO软件的快速多极化动态RCS仿真方法。首先通过静态目标多极化回波仿真得到全空域RCS数据,再根据预先设定的两种航迹,经过坐标转换得到雷达相对于飞机的实时方位和俯仰角,最后通过仿真得到HH,VH,VV和HV 4种极化方式的动态RCS序列。仿真结果可为目标隐身与反隐身技术研究提供参考。Aiming at the problem of building the model of dynamic and static multi-polarization ech- oes of radar target, a method of simulating dynamic multi-polarization RCS by FEKO is proposed. Firstly, RCS data of total space is obtained through static multi-polarization echoes simulation. Secondly, plane＇ s attitude angel is obtained through coordinate transformation by the two certain tracks in advance. Lastly, the dynamic RCS of HH, VH, VV and HV four polar types are calculated by simulation. The simula- tion results can provide a support on studying the technology of stealth and anti-stealth.
