摘要
分别给出平行极化和垂直极化平面波入射到圆柱体时产生的散射场通用公式及其散射参数定义式，对金属圆柱体带有不同厚度的欠密状态等离子体层，过密状态等离子层，有损耗介质层等条件下的ＲＣＳ计算进行了全面的数值分析，分析了影响双站ＲＣＳ的各种因素并给出了数值结果，获得一些有用的结论，为进一步研究再入体的散射机理提供有用的参考．
The general formulas of the scattering field and scattering parameter definition when the parallel and vertical polarization plane wave respectively incident on the cylinder are given.The radar scattering cross section(RCS) of the metal cylinder coated with undensed plasma,densed plasma and loss material are numerically analyzed.Bistatic RCS of conduction cylinder is analyzed comprehensively and each factor affecting its RCS is also analyzed.Some numeric result and useful conclusion obtained are given,which offers useful reference for studying scattering mechanism furtherly from reentry.
