现代雷达信号朝着多格式、多频段、大带宽趋势发展,对电子战中雷达信号侦测提出了更大挑战,要求接收机具备大瞬时带宽、宽频谱覆盖以及高频谱分辨能力。微波光子技术因其具有低损耗、大带宽、抗电磁干扰、设备结构简单等优势,与超宽带信道化接收需求相匹配。本文从信道化接收机面临的需求与挑战出发,对众多微波光子信道化接收机技术方案进行简要梳理,然后介绍了目前微波光子信道化接收机技术发展方向。

Modern radar signal is developing towards multi-format, multi-band, and large bandwidth, which poses a greater challenge to radar signal detection in electronic warfare, and requires receivers with large instantaneous bandwidth, wide spectrum coverage, and high spectrum resolution ability. For the advantages of low loss, large bandwidth, anti-electromagnetic interference, and simple structure, microwave photonic technology meets the requirements of ultra-wideband channelized receivers. Starting from the needs and challenges faced by channelized receivers, typical technical schemes of microwave photonics channelized receivers are briefly reviewed, and current research trends of microwave photonics channelized receiver technology are introduced.
