| 摘 要： | 针对求解目标近区电磁散射特性,提出基于物理光学法和面元法计算目标近场雷达截面积(RGS),即采用目标形体构造的面元法建立目标的表面模型,利用物理光学法计算目标近区场上的每单元的散射场,而后对所有单元的散射场矢量求和得到整个目标的散射场和雷达散射截面(RCS).将目标的RGS计算结果代人引信电路仿真模型获得的目标多普勒信号和引信启动点与实测结果的统计特性一致,证明该方法具有实用性.

| Abstract: | A new method is put forward for calculating near-field electromagnetic scattering and near-field RCS,which is based on physic-optics(PO) method and panel method.Detailedly,targets is modeled by penal method,the near-field electromagnetic scattering of each unit is calculated,and finally the results are added up to get the scattering and RCS of the whole target.Then the RCS result is substituted into the fuze circuit model to get the Doppler signal of the target and the fuze initiation point both of which ar... |
