摘　　要：本文研究粗糙面球面波近场散射效应 ,分析计算了理想条件下由于路径相关引起的干涉效应 ;用带限分形函数来模拟二维粗糙表面 ,从动态和静态角度 ,揭示在许多不同条件下粗糙面单站近场散射的物理机理。A study on the near-field scattering of Spherical Wave from the rough surface has been made.The analysis and calculation are started from path-different rough surface case.The rough surfaces are modeled by the band limit fractal function. Results show the predicted Fresnel zone interfering phenomenon. The physical mechanism for the change of the near-field backscattering coefficients with the different platform altitude is explained from a lot of different aspects.
