Abstract

Optoelectronic oscillator (OEO) is a high-quality microwave source that can generate various forms of microwave signals, and structures for generating complex signals using OEO are constantly being proposed. We propose an OEO-based microwave pulse generation system where each sub-pulse is composed of random signal. The random fiber bragg gratings(R-FBG) were introduced to generate the random signal by using the OEO vibration characteristics. The output characteristics of the OEO loop are then modified by modulation of the bias voltage, thereby changing the output characteristics of the OEO loop. Finally, the present OEO system generates random microwave pulse signals with adjustable pulse envelopes, adjustable duty cycles and adjustable repetition rates.

基于随机光电振荡器的随机微波脉冲的产生

光电振荡器（OEO）是一种可以产生多种形式微波信号的高质量微波源，利用OEO产生复杂信号的结构不断被提出。提出了一种基于oeo的微波脉冲产生系统，其中每个子脉冲由随机信号组成。引入随机光纤bragg光栅（R-FBG），利用OEO振动特性产生随机信号。然后通过调制偏置电压来修改OEO环路的输出特性，从而改变OEO环路的输出特性。最后，本系统产生具有可调脉冲包络、可调占空比和可调重复率的随机微波脉冲信号。
