摘　　要：建立了用物理光学计算复杂目标近区散射特性的理论模型,利用像素法及面片法计算了典型形体及几种复杂目标近区RCS.结果表明复杂目标近区RCS特性与其远区相比有很大不同,近区RCS特性要复杂得多.这项研究在现代战争中有重要的工程价值.The theory model about computing complex targets near-field electromagnetic scattering is established using PO (Physics Optics). And the near-field RCS from some typical bodies are computing using the picture elements (PEL) method and cell method. The calculated results show that there are much difference between the near field and the far field. And the characteristics of the near field are more complex. This work has practical engineering value in the modern and high science and technology warfare.
