摘要
精确制导技术是精确制导武器的核心技术。为了实现精确目标打击,制导系统必须具有高分辨能力和抗干扰能力。目前的制导技术发展趋势可以总结为更高更宽,高是指更高的工作频率,宽是指更宽的工作带宽。但是电子技术的瓶颈逐渐显现,尤其在信号产生方面,这从源头上限制了雷达制导性能的提升。利用微波光子技术实现微波信号的产生与处理,实现大带宽的任意波形信号,可有效解决电子瓶颈问题。微波光子雷达同时具有光子和微波技术的优势,因此研究基于微波光子的新型制导技术具有先进性和挑战性,且具有很强的应用背景。
Precision guidance technology is the core technology of precision guided weapons.In order to achieve accurate target strike,the guidance system must have high resolution and anti-jamming ability.The current development trend of guidance technology can be summarized as higher operating frequency and wider ope-rating bandwidth.However,the bottleneck of electronic technology is gradually emerging,particularly in signal generation,which limits the improvement of radar guidance performance from the source.Using microwave photon technology to generate and process microwave signals and realize arbitrary waveform signals with large bandwidth can effectively solve the electronic bottleneck.Microwave photonic radar has the advantages of both photon and microwave technologies.Therefore,the study of new guidance technology based on microwave photon technology is advanced and challenging,and also has a strong application background.
