| 摘 要： | 提出了在超宽带射频仿真系统中三轴转台的低RCS设计方法.该方法采用转台机械结构设计、低RCS外形优化分析与测试测量相结合的方式.首先基于低RCS要求及三轴转台的结构特性,对其进行外形优化.通过计算三轴转台的表面感应电流分布,分析三轴转台的强散射区域,并选取相应吸波材料及涂敷方法对三轴转台进行处理.实际测量表明,涂敷吸波材料后三轴转台散射回波幅度显著减小,分布均匀,达到了预设的效果.

| Abstract: | Low radar cross section(RCS) design method for three-axis turntable in radio frequency simulation system(RFSS) with large relative bandwidth is studied.Turntable mechanical structure design,low-RCS shape optimization analysis,and combination of test and measurement are used in the method.First,based on low RCS and the mechanical properties of three-axis turntable,its shape is optimized.Then,the surface-induced current distribution of turntable is computed and strong scattering regions are analyzed.Finally,s... |
