Generation of Random Microwave Pulse Based on Random Optoelectronic Oscillator

Year: 2025

Type: article

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.
