基于光纤延时环路的单脉冲接收机

A Single Pulsed Receiver Based on Optical Fiber Delay Loops

针对国外学者提出的基于光纤延时环路的高分辨多普勒接收机,深入分析了利用光学延迟环路复制脉冲串的信号检测方法。并在此基础上分析了两种可能的应用形式:单脉冲多普勒检测和单脉冲自相关检测,并为两种方法提供了单脉冲接收机的基本结构和试验参数。研究表明,基于光纤环路延时的单脉冲处理,本质上仍是一种通过光学拉长的方法实现了单脉冲的高速采样。

A method of realizing the single pulsed receiver by optical fiber delay loops is dis- cussed, which includes a reflected pulse from target is dealt with through doppler and an un- known pulse is dealt with through auto correlation. And related parameters for a prototype are al- so discussed. Research results show that single pulse processing by loop delay is essentially real- ized by high speed pulse sampling through optical stretch.
