摘要
进行了矩量法在计算涂敷目标雷达散射截面方面的研究。详细推导了将RWG基作为基函数时,任意涂敷目标的电磁流方程表达式。鉴于矩量法计算量过大,耗时太长,使分析与优化遇到实质性的困难,结合RWG基函数特点,在对具体的矩阵方程求解时采用了并行处理。通过计算结果和精确结果对比,证明了此种方法的准确性和有效性,同时并行方法的使用大大降低了计算时间。
Researching the calculation of RCS about coated targets, use MOM with the RWG basis function, detailed derivation of the expressions of the electric and magnetic currents. Because the prohibitive computation resources and too much time are needed for RCS analysis of complicated coated targets, we combine the RWG basis function characteristics, adopt the parallel methods to solving the matrix equations. By calculating the precise results and the results compared to prove that this kind of methods accuracy and effectiveness, and the use of parallel methods greatly reduce the computation time.
