高压线后向散射极化分析

Analysis of Back Polarization Scattered by the High Voltage Wire

用无限长导体圆柱模型代替理想高压线,应用物理光学法(po)计算高压线的后向散射矩阵,并讨论某频率入射波、某入射角下的最优化情形以及目标特征参数和入射角之间的关系,给出相应的数值结果,改善直升机识别效果。

Replace the ideal High Voltage Wire with the infinite length conducting cylinder model, with the method of physics optics （PO） ,the formulas of back polarization scattering matrix（PSM） for High Voltage Wire is presented. According to the PSM, the characteristic parameters that change with the incident angle and the optimization of it for some incident frequency are analyzed. The simulation results are given which prove the effect of identification for helicopter.
