利用光源体积较小且容易实现的特点,提出了将微波大尺度缩比到可见光波段,采用光源辐射产生的光波缩比测量目标在微波频段雷达散射截面的思想,讨论了由此带来的原型系统中目标几何尺寸不能缩得很小而导致的必须变电长度缩比问题,深入研究了在这种非等比的非精确相似条件下目标雷达散射截面的相似性关系,以及符合这种相似性关系的微波-光波变电尺度缩比仿真雷达散射截面的约束条件和补偿方法.研究成果为在实验室等较小场地实现大型电磁系统缩比仿真测量实验提供了新思路.
Based on the characteristics of small and easy-to-use light source, the idea of reducing the microwave scale to the visible light band is proposed. The idea of measuring the target radar cross section in the microwave frequency band by using the light wave reduction generated by the light source radiation is discussed. In the system, the target geometric size can not be reduced to a very small extent, which leads to the problem of the required transformer length reduction ratio. The similarity relation of the target radar cross section under such non-exact analogous non-exact similarity condition is studied in depth.
