| 摘 要： | 给出了一种快速计算复杂涂敷目标散射场的方法。将复杂目标电磁散射分成面元和边缘散射,运用物理光学(PO)、阻抗边界条件(IBC)、等效电流(EM C)和物理绕射理论(PTD)对复杂目标雷达散射截面(RCS)进行计算,并将计算结果与文献结果及无涂敷纯金属目标的RCS进行对比分析,结果与文献及预期估计情况吻合较好,表明该方法不仅计算简单,而且结果也较为精确。

| Abstract: | A fast method for calculating the scattering field of the complex target coated with radar absorption material(RAM) is given.The target is divided into several surfaces and edges,and the radar cross section(RCS) is calculated using physical optics,the impedance boundary condition(IBC),the method of equivalent current(MEC) and the physical theory of diffraction.Compared with the RCS of the target without RAM and the result in related literature,the obtained result agrees well with the result in literature and the prediction,which shows that the presented method is simple and the obtained result is rather exact. |
