摘　　要：利用雷达波在介质中传播时的等效传输线理论,分析了雷达波垂直入射到Salisbury屏时的反射系数及相关计算公式,并基于MATLAB软件按照全貌分析方法对隔离层掺杂了纳米稀土氧化物的Salisbury屏中介电常数、磁导率等参数与反射率进行了讨论及优化设计.结果表明:在雷达波吸收材料的设计时磁损耗的优化起主要作用;隔离层掺杂了纳米稀土氧化物后提高了Salisbury屏在2~18GHz频段吸收雷达波的性能;在该频段的后向反射率衰减值大于7dB,能够满足国防军事中的雷达波隐身基本要求.Using the equivalent transmission line theory of radar wave propagation in the medium,the reflection coefficient and the related calculation formula of the radar wave are analyzed at the vertical incidence to Salisbury screen.Based on the MATLAB software,the panorama analysis method is used to discuss and design the electric constant,permeability and reflectivity of Salisbury screen at the isolation layer doped with nano rare earth oxides.The results showed that the optimization of magnetic loss plays an important role in the optimized design of radar absorbing materials.The isolation layer doped with nanometer rare earth oxide improves the performance of Salisbury screen for the radar wave absorption in the frequency band 2~18 GHz.The backward reflectance attenuation value is greater than 7 dB,which can meet the basic requirements of radar wave stealth in national defense and military.
