摘　　要：提出一种基于可拓展光域频谱操控模块(OFOM)的多波段宽带线性调频(LFM)信号并行产生方法,通过复制第二级光谱操控架构实现多路雷达信号并行产生。针对该方法,进一步探讨了光域频谱操控模块输出信杂比的优化方法。相比于传统多波段信号并行产生方法,所提方法不仅可同时产生超宽带的双波段信号,而且所产生信号参数可独立调谐,同时系统结构简单、可靠性高。在实验中,利用所提方法并行产生了从甚高频(VHF)波段到X波段的双波段信号,带宽可从2.4 MHz调谐到6 GHz,同时能在低频段产生1.2 GHz的大带宽信号。该技术可应用于未来雷达系统,极大地提升系统性能和扩展功能。We propose a parallel generation method for multi-band linear frequency modulated(LFM)signals based on an extensible optical frequency operation module(OFOM).By replicating the second-stage spectral manipulation architecture,we achieve the parallel generation of multiple radar signals.Additionally,we discuss the optimization method for the output signal-to-clutter ratio(SCR)of OFOM.Compared to traditional methods for parallel multi-band signal generation,the proposed method not only simultaneously generates ultra-wideband dual-band signals but also allows for independent tuning of the generated signal parameters,while maintaining a simple and reliable system structure.In our experiments,we use this method to generate dual-band signals ranging from the very high frequency(VHF)band to the X-band,with bandwidths adjustable from 2.4 MHz to 6 GHz,and capable of producing large bandwidth signals of 1.2 GHz at low central frequencies.This technology holds potential applications in future radar systems,significantly enhancing system performance and expanding functionalities.
