用矩量法对一些用于雷达隐身技术和微波暗室设计的大损耗介电材料填充的无限长介质圆柱在TM波照射下的双站RCS进行了数值计算 .仿真结果表明 ,大介电常数低损耗材料散射较弱 .当ka0 较小时 ,填充介质的电参数对散射的影响较明显 ,且随双站角增大缓慢减少 ;当ka0 较大时 ,填充介质的电参数对散射的影响不明显 ,且散射能量集中于反射方向
The moment-invariant method is used to calculate the bistatic RCS of some infinite dielectric cylinders filled with large loss dielectric materials used in radar stealth technology and microwave anechoic chamber design under the TM wave irradiation. The simulation results show that the low dielectric constant When ka0 is small, the influence of the dielectric parameters of the filler medium on the scattering is obvious and decreases slowly with the increase of the bing station angle. When the ka0 is large, the influence of the dielectric parameters of the filling medium on the scattering is insignificant , And the scattering energy is concentrated in the reflection direction
