| 摘 要： | 建立了箔条目标模型,得出了箔条目标散射场的解析解,为研究箔条目标的电磁波极化特性奠定了理论基础;研究了电磁波平行投射到箔条上与垂直投射到箔条上的散射特性;结果表明:无论是前向散射还是后向散射,箔条形状的变化对散射特性有着明显的影响,都具有后向散射增强效应,箔条在某一方向上的散射基本上由正对该方向的目标上的电磁源决定。

| Abstract: | The model of chaff is constructed and its analytic solution of scattering field is presented,which established a base in theory for investigating the polarization of the chaff.The scattering characteristics are studied when the propagating direction of the incident wave is parallel and vertical to the chaff respectively.Simulation shows that the shape parameters influence markedly the scattering properties for the forward scattering and the backward scattering and there is an effect of enhancement for backward scattering.The scattering characteristic to a direction is determined chiefly by the electromagnetic sources on the surface of chaffs which is dead against that direction. |
