摘　　要：以二维问题为例 ,基于平面波谱展开理论和几何光学近似 ,利用计算机模拟的方法研究了暗室墙壁散射对超低副瓣天线平面近场测量的影响 。With a two dimensional problem as an example, the effect of scattering from wall of anechoic chamber on planar near field measurements with ultra low sidelobe antennas is studied by means of computer simulation based on theory of plane wave spectrum expansion and approximation in geometrical optics.Some basic laws and useful results are obtained.
