雷达目标宽带散射特性的 GGO 快速分析方法
Fast analysis of wide-band scattering from radar targets using the GGO method
摘要
Abstract
The dimensions reducing technique combined with the Maehly approximation is applied to the Method of Moment ( MoM ) for analysis of the two-dimensional radar cross section ( RCS) of the target . The Gauss-Green-Ostrogradsky ( GGO ) algorithm is utilized to transform the two-dimensional expression for the surface currents in both spatial and frequency domains to one dimension and its derivatives . This procedure avoids the solution of expansion coefficients in the two-dimensional expression and makes the accuracy adjustable by the order of derivatives . Compared with the two-dimensional Maehly approximation method , the proposed scheme can acquire RCS data efficiently with good accuracy and reduce procedural complexity . Finally , numerical results show that memory requirement and calculation time are about 1/6 and 1/3 of what are needed in the original method .关键词
