摘要

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.

Abstract

According to small size and easy-to-realize features of visible light radiator, a new idea of adopting light wave produced by light radiator models to measure an object microwave radar cross section (RCS) at big scale factor is presented. The similitude of object RCS in inequal electrical length condition is discussed. The constrained condition and compensation process for such a model measurement are also provided.
