| 摘 要： | 用物理光学法研究导电平板目标近场散射特性，为了提高计算效率，文中采用了卷积积分法．通过计算机的模拟发现，当特征尺寸、入射场波长及观察点离目标的距离改变时，其散射场存在一定的换算关系，散射场出现近似的或严格的相似性

| Abstract: | The near\|field scattering characteristics for the conduct plate is studied by using of the physics optics method, and a calculation method of convolution integration for near field scattering is discussed. This method can accomplish fast calculation by FFT. With the changes of plate characteristic, size wavelength and the distanc from the observation plate to the scattering body, found by computer modeling, the scattering field exists a relation, and there are two different similarities in the scattering field distribution, the strict similarity when electronical size is constant and the asymptotic similarity when it changes. |
