基于 FEKO 的典型吸波结构 RCS 缩减研究

内容简介：采用以矩量法为基础的软件FEKO对典型模型的雷达散射截面积（RCS ）进行仿真，并与实验结果进行对比分析。针对典型结构模型，选择层板型吸波材料，在6G Hz的RCS缩减实验结果达到-6．8dBsm ；选择蜂窝-层板型吸波材料可大幅度改善吸波性能，其在6GHz的RCS缩减实验结果为-12dBsm。分析表明，FEKO软件对典型结构模型的仿真计算结果与实验测试结果基本一致。

Abstract：The simulation analysis for radar cross section(RCS) of the typical model is carried out using software FEKO based on method of moment .For the typical structure model ,the RCS reduction of the wing model can reach to -6 .8dBsm at 6GHz when plate type absorbing material is chosen .And the absorbing properties can be greatly improved when honey-comb-plate sandwich type absorbing material is chosen ,the RCS reduction can reach to -12dBsm .In the end ,the analysis indicates that the simulation results of the typical structure model by software FEKO and the experimental results are basical-ly in agreement .
