摘要
提出了快速分析导体雷达散射截面的稻垣模和广义渐近波形估计综合技术.该新技术利用稻垣模的正交性和完备性,构建出矩阵方程的解空间,用一组系数将解空间基矢组合起来得到方程的解,在给定频点,这组系数通过广义渐近波形估计技术来确定.算例结果证明了新技术计算雷达散射截面的有效性.
The hybrid technique to integrate the Inagaki modes with the general as-ymptotic waveform evaluation（GAWE） is proposed for computing the radar cross section（RCS） of a perfect electric conductor（PEC）. In the analysis, the orthogo-nality and completeness of the Inagaki modes are used to construct the solution space of a matrix equation. Hence, the solution of the equation can be obtained by combining the based-vectors of the solution space with a set of coefficients, which can be determined by the GAWE technique at a given frequency. The results of nu-merical examples verify that the novel technique is effective in computing RCS.
