| 摘 要： | 研究了角反射器表面粗糙度对其雷达散射截面的影响.角反射器的粗糙表面由随机高斯面模拟,散射计算采用全波数值算法完成.计算结果与实测数据吻合,对实验数据进行了解释,验证了计算模型.通过多组计算结果得出结论,随着粗糙面均方根高度的增加和相关长度的减小,角反射器的非主散射区雷达横截面(RCS)均值提高,到达一定数值后角反射器的主散射区RCS也将受到显著影响.研究结论对角反射器用于RCS标定具有重要应用意义.

| Abstract: | The effect on RCS caused by surface roughness of the corner reflector is analyzed in this paper.The rough surface was modeled by Gaussian random surface and the scattering field was computed by full-wave numerical method(FE-BI-MLFMA).The numerical results agree well with the measured data,which clarifies the experimental data and validates the computation model.Several sets of numerical results show that the average RCS of the side-scattering region increases with the raise of root mean square height or the... |
