摘　　要：用微波光子技术实现微波信号频率的瞬时测量,需要把截获的微波信号调制到光载波上,通过一定的光路结构,产生一个仅与待测微波信号频率有关的幅度比较函数,进而得到待测微波信号的频率。研究了微波光子技术在雷达瞬时测频应用中的实现方法,分析比较了各自的功能特点,并提出了一种结构简单的雷达微波信号全频段测量方法。It is necessary to modulate the unknown microwave signal to optical carrier wave in order to measure microwave signal frequency instantaneously with microwave photonic techno-logy,and modulated optical carrier going through certain optica-fiber structure,an amplitude comparison function only related to microwave signal frequency could be obtained,so that microwave signal frequency can be worked out.The application of microwave photonic technology in radar instantaneous frequency measurement is investigates and several typical structures are analysed and compared respectively.Futhermore,a method with simple structure to achieve radar signal＇s full-band measurement is instroduced.
