摘要 对一种飞翼布局无人机(UAV)模型的雷达散射截面(RCS)进行了理论仿真估算和微波暗室测量。在仿真估算中采用了一种物理光学法(PO)+等效电磁流(MEC)法的混合高频计算方法,分别针对目标表面散射和目标边缘散射场进行计算。得出的理论结果与真实测量结果基本相符,证明在解决电大尺寸模型的RCS估算时以这种方法计算具有较高的可信度,能够满足仿真要求。 The RCS of a UAV model is researched by testing in anechoic chamber and simulation computing. A mixed algorithm PO+MEC is provided. Physical optics calculation (PO) is used to compute the surface scattering of targets, and the method of equivalent currents(MEC) is used to compute the wedge scattering of targets edge. According to this algorithm, the RCS computation results of the UAV model obtained basicly agree with the testing results. It proves that the algorithm used here is effectual for disposing large electrical model.
