雷达散射截面积（RCS）的 FD TD 研究*

摘要

Calculation of the various media of electromagnetic scattering problems in the electromagnetic irradiation ,is an im‐portant application of finite difference time domain method .Especially in the early age of the method ,FDTD is always connected with scattering problems .This paper introduces and analyzes a simple application of FDTD method in calculating the radar cross section . The simulation results show that the FDTD method has a great advantage in calculating object's RCS .%计算各种媒质在电磁波照射下的散射问题，一直是FDTD算法应用的一个重要方面，特别是在FDTD技术发展的初期，它几乎总是和散射问题联系在一起。论文简单介绍并分析了时域有限差分法在计算雷达散射截面积（RCS ）中的应用，仿真结果表明FDTD在计算物体RCS方面有很大的优势。
