摘要
光纤延迟环型射频存储技术因其大瞬时带宽、快速响应能力等优势在电子干扰领域备受关注。为了实现复杂脉冲信号的多样式存储,先后实现了移频型、门控半导体光放大器(SOA)型、级联型等不同光纤延迟环结构,通过对延迟环结构的对比分析和优化设计,获得了高保真、高分辨率、长时延、脉宽可重构的多功能存储方案。级联存储结构,实现了超过2000次脉冲复制、大于500μs的高分辨率长时延存储,以及200 ns^10μs的脉宽重构,可广泛应用于大范围脉宽、快速长时延存储和复杂调制格式等不同场景中。
Optical delay-time loop-based radio frequency(RF)memory technology has received considerable attention in the field of electronic jamming owing to its broad instantaneous bandwidth and fast response time.To obtain a multipattern memory of complex RF pulse signals,different types of optical delay-time loop-based memory structures such as frequency shifting type,gated semiconductor optical amplifier(SOA)type,and cascade type have been successively realized.Through the comparison and optimization of delay-time loop-based structures,the storage schemes with high fidelity,high resolution,long delay and the reconfiguration of pulse width can be realized.More than 2000 pulse replications,storage with high resolution and time greater than 500μs,and 200 ns--10μs pulse-width reconstruction can be achieved in the cascaded structure,which can be applied in different application scenarios such as a wide range of pulse widths,complex modulation formats,and fast and long delay storage.
