摘要
针对传统测频接收机不足,利用声光偏转效应,设计出了一种测量雷达载波频率的方法,实现了雷达告警。进行了实验模拟,分析了系统工作原理和性能。实验表明利用声光器件的雷达告警系统能够实时、并行处理多个频段信号,具有反应快、带宽大、精度高等特点,具有较大的应用潜力。
To overcome the deficiency of traditional frequency meter, a convenient way is found for measuring cartier frequency of radar by use of acousto - optic deflection effect, and therefore to realize radar warning. We made some experimental simulations, and analyzed the operational principle and performance of the system. The experiments showed that the radar warning system using acousto- optic deflection effect can process parallel signals of multiple frequency bands in real time, and has the characteristics of quick response, wide bandwidth and high precision. It has great potential applications in radar warning.
