摘要
由电场积分方程出发,以矩量法为基础,应用广义屋脊基函数R W G基和加略金匹配法,并应用快速多极子方法,推导出简单而且有效的R C S计算公式,以全矩量法计算结果作为检验标准,证明了快速多极子方法计算结果的正确性。在300M H z频率给出了快速多极子方法在计算时间和占用内存方面的效率,并进一步计算了更高频率时的战斧导弹的R C S值。
The method is based on the moment method(MoM), EFIE and the fast multipole method (FMM). The objects were modeled using planar triangular surfaces patches. This method is simple and effective to solve the scatter problem and its numerical result has exact precision. A missile were shaped and computed, and the results showed and analyzed.
