多分辨预处理技术加速PO—MOM混合方法的研究

摘要

In view of the calculation of electromagnetic scatter for the complex object, the hybrid technology that combines physical optics （PO） with moment method （MOM） is investigated, which search for the way of the reduction computational time and memory requirement and the improvement the calculative precision. The multi-resolution pre-processing technology is introduced for the iterative problem during solving the problems by MOM, and the calculation examples are given. The results show that the calculation efficiency is improved in the same accuracy by the hybrid method of PO-MOM.%结合复杂物体散射特性的电磁计算问题，研究了物理光学（PO）与矩量法（MOM）相结合的混合技术，寻求PO-MOM方法减少计算时间和存储空间、提高计算精度的途径；针对矩量法在求解过程中的迭代问题，引入多分辨预处理技术，并给出算例．结果表明，在满足计算精度不变的前提下，使用PO-MOM混合方法提高了计算效率．
