摘要:
针对宽带微波光子雷达易被外界电磁信号干扰,难以在复杂电磁环境下对多样化目标进行高速探测与识别的关键难题,本文提出一种能融合多个机会频带以实现高分辨率探测的微波光子认知雷达系统架构。探讨了与微波光子认知雷达系统相关的微波光子宽带实时频谱侦测、可重构波形产生和稀疏频带成像处理等关键技术,论证了方案的可行性。该方案充分发挥了光子技术的宽带承载、实时处理以及灵活可重构的优势,可同时提升雷达的分辨率和环境适应能力,有望为未来智能化装备提供清晰、可靠、智能的全天候探测手段。

Abstract:
Due to the broadband nature, microwave photonic radars are vulnerable to external electromagnetic interference and therefore difficult to work in complex electromagnetic environment. This paper proposes a novel microwave photonic cognitive radar that can achieve high resolution detection using multiple opportunistic sparse frequency bands. Key techniques for the microwave photonic cognitive radar, such as real time and broadband microwave photonic spectrum monitoring, reconfigurable waveform generation, and sparse imaging are discussed. The feasibility of the radar architecture is demonstrated. The microwave photonic cognitive radar takes benefits of the broadband operation, real time processing capability and dynamic reconfigurability of photonics, and can realize high resolution detection and good environment adaptiveness simultaneously. It will provide a clear, reliable, intelligent and all weather target detection method for automatic drive, security monitoring, space debris management and so on.
Key words:  sparse imaging  cognitive radar  spectrum monitoring  microwave photonic radars
