充气式角反射器制作偏差对RCS特性影响的仿真研究
|
摘要
二十面体充气式角反射器是重要的雷达干扰器材,三面角反射器是其基本组成单元。角反射器的制作偏差对其雷达截面积(RCS)特性有显著影响,因而研究三面角反射器制作偏差对其RCS特性的影响有重要意义。该文采用数值仿真方法研究了制作偏差对RCS特性的影响。首先验证了仿真方法的精度,利用该方法分别计算了角度偏差、顶角开孔、角反射布局部褶皱、导电性能和面轮廓度对三面角反射器RCS的影响。结果表明,角度偏差和面轮廓度对三面角反射器RCS的影响最为显著。
The inflatable icosahedral corner reflector is an important radar jamming equipment,and the trihedral corner reflector is its basic element. The manufacturing deviations of the trihedral corner reflector have important influences on radar cross section(RCS)characters,so the study on the effect of manufacturing deviation of the inflatable corner reflector on the RCS characters is meaningful to its manufacture,check and application. In this paper,the RCS characters are studied by using the numerical simulation method,and the accuracy of the method is verified firstly. Then the effects of angular deviations,the hole on the corner angle,the wrinkle and conductivity of the metal cloth,and the surface profile of the cloth on the triangular trihedral corner reflector are studied in details. The result shows that the angular deviations and the surface profile of the cloth have significant effects on the RCS characters of the trihedral corner reflector.
