摘要： 从电场积分方程出发,以三角屋顶(RWG)函数为基函数导出了任意均匀各向同性材料部分涂覆导体目标矩量解的表达式,给出了矩阵元素的计算公式,提出了数值计算中应作的特殊处理,得到了材料涂覆导体目标RCS的一般计算公式,并利用渐近波形估计(AWE)技术实现了材料部分涂覆导体目标电磁散射的宽频快速估计,从而提高了计算效率.

Abstract: With the electric field integral equations as the basis, a moment method formula is derived for calculating the RCS of arbitrarily partially coated conducting objects by using triangle-roof-top function as the basic function. Some special numerical treatments have been proposed for improving the calculation accuracy. The asymptotic waveform evaluation(AWE) technique combined with the method of moments, is applied to evaluate the RCS of arbitrarily partially coated conducting objects in a wide band. The numerical results show that the special treatments proposed here can improve the accuracy and the AWE can increase the computational efficiency.

Key words: asymptotic waveform evaluation, partially coated conducting object, radar cross section, method of moments
