分析半空间目标短波散射的一种近似方法

An Approximate Method for HF Scattering by Target in the Half Space

本文讨论半空间中目标后向散射计算的一次反射近似方法．并且利用互易原理和等效偶极子模型进一步简化了计算．数值例子验证了所述近似方法的适用性．本文方法可应用于短波超视距雷达海上目标散射特性的分析．

In this paper we present the first order reflection approximation (FRA) method for half space backscattering problem.Further use of the reciprocity theorem and an equivalent dipole model may notably simplify the computation.Numerical results show the feasibility of presented scheme.This method can be applied for the analysis of scattering problem of a target above the sea surface for HF over the horizon radar.
