| 摘 要： | 采用矢通量分裂法在网格加密后对电磁散射场和雷达散射截面积RCS进行了检验.根据矢通量分裂法将特征值分解为正负两部分,每一部分抑制了各自的误差.目前计算RCS大都采用频域方法,运用时域方法在实际网格下进行差分运算还较少见.计算结果与网格加密前的情况基本一致.

| Abstract: | The paper focus on tests on electromagnetics field and Radar Cross Section (RCS) with densified grid provided by the flux splitting method.It separated the representative value into positive and negative part in order to hold down the allowance errows respectively.For the purpose of optimization design computation,the time domain scheme is applied to calculate RCS,the final results agree satisfitorily compareing with previous results. |
