【摘要】：雷达是人类进行全天候目标探测与识别的主要手段,多功能、高精度、实时探测一直是雷达研究者追求的目标。这些特性实现的基础都是对宽带微波信号的高速操控,但受限于"电子瓶颈",宽带信号的产生、控制和处理在传统电子学中极为复杂甚至无法完成。光子技术与生俱来的大带宽、低传输损耗、抗电磁干扰等特性,使其成为突破雷达带宽瓶颈和"照亮雷达未来"的关键使能技术。同时光子系统重量轻、体积小、可集成,可以将雷达系统的体积重量降低数十倍,从而大大减轻飞机、卫星、舰艇等的载荷。因此光子技术的引入有可能改变现有雷达系统的体制,赋予雷达系统更加蓬勃的生命力。本文总结了国内外光子雷达系统的主要研究进展,讨论了光子雷达系统中的关键技术,并展望了光子雷达及其关键技术的发展趋势。
[Abstract]:Radar is the main means of all-weather target detection and recognition. Multifunctional, high-precision and real-time detection is always the target pursued by radar researchers. The realization of these characteristics is based on the high-speed manipulation of wideband microwave signals. However, due to the "electronic bottleneck", the generation, control and processing of wideband signals are extremely complex or impossible in traditional electronics. Photonic technology has inherent characteristics such as large bandwidth, low transmission loss, anti-electromagnetic interference, and so on. Making it a key enabling technology to break through the bottleneck of radar bandwidth and "illuminate the future of radar." at the same time, the photon system is light, small and integrated, which can reduce the volume weight of radar system by tens of times, thus greatly reducing aircraft and satellites. Therefore, the introduction of photon technology may change the existing system of radar system and give the radar system more vigorous vitality. This paper summarizes the main research progress of photon radar system at home and abroad. The key technologies of photonic radar system are discussed, and the development trend of photonic radar and its key technologies are prospected.
