介质涂复旋转体雷达散射截面的数值计算方案

A Numerical Scheme to Obtain the RCS of Dielectric Coated Bodies of Revolution

该文提出一种计算介质涂复旋转体雷达散射截面(RCS)的数值计算方案。RCS是通过矩量法求解进一步减少未知数的表面积分方程得到。与原始的表面积分方程相比,这种方案明显节省了计算机内存和CPU时间。因为对RCS计算,这里仅需确定在最外层表面上的表面流。

A Numerical scheme to obtain the RCS of dielectriccoated bodies of revolution is described. In this scheme, the RCS isobtained by solving surface integral equations with further reduction ofunknowns, using the momemt method. In comparison with ordinarysurface integral equations, significant savings in computer storage andCPU time are realized, since only surface currents on the outer surfaceshould be determined for RCS evaluation.
