| 摘 要： | 介绍了啁啾光纤光栅延迟线在光控相控阵雷达中的两种应用系统及其工作原理，即基于单波长激光器和多个可调啁啾光纤光栅延迟线的系统以及基于多波长激光器和一个可调啁啾光纤光栅延迟线的系统。介绍了这两种系统的光控相控阵雷达扫描角要实现连续变化时，啁啾光纤光栅延迟线的调谐原理。分析结果表明，若啁啾光纤光栅的长度长而反射谱窄，则啁啾光纤光栅较小的调谐量就能使光控相控阵雷达天线实现较大的扫描范围。

| Abstract: | Two systems and their operation principles of time-delay line of chirped fiber grating(CFG)applied to optically controlled phased array radar are introduced.One system is composed of single wavelength laser and some tunable chirped fi- ber gratings,and the other system is formed of multi-wavelength laser and single tunable chirped fiber grating.The tuning principles of chirped fiber grating are simply studied.The analysis result shows that if chirped fiber grating is long enough and its reflectivity width i... |
