提出一种有限微带阵列电磁散射特性分析的有效方法。该法采用有限阵格林函数与矩量法相结合的方法，有效地解决了矩量法在大型阵列电磁特性分析中的计算效率问题；通过选取RWG基函数，使该法适用于任何单元形状的微带阵列。文中计算了矩形、十字形及圆形单元微带阵列的雷达截面，并与常规矩量法和参考文献的计算结果进行了比对，验证了该方法的有效性。

An effective method for analyzing the electromagnetic scattering from finite microstrip array is proposed.It combines the finite array Green's function with the method of moment,and effectively improves the computation efficiency of the analysis of electromagnetic scattering by a large finite microstrip array.This method can be adapted to microstrip arrays with arbitrarily shaped elements by choosing RWG basis functions.In this paper,radar cross section of arrays with rectangular,cross-shaped and circular element is computed and the results are compared with the that of method of moment to validate this method.
