采用伽列金矩量法,对线状散射体的电磁散射问题进行了分析,综合分域基函数和全域基函数的优点,在幂级数函数的基础上,形成了一种简便有效的混合域基函数作为基函数和检验函数,并根据该混合域基函数,对简单形体的线状散射体的雷达散射截面进行了仿真。结果表明,该基函数简单有效,计算结果准确,有利于计算机的快速求解。

An efficient and simple hybrid domain basis function based on power series functions is formed that acts as the sub-domain and entire domain basis function in the process of the EM scattering problems analysis of the wire scaterers,and this function is taken as the basis function and test function with the Galerkin-MOM.By this method,the radar cross section was calculated for three kinds of wire scatterers.The final results indicate that there is a good agreement between the measured results and calculated results,and also prove that the function used in this paper is very efficient.
