摘要
研究了连续混沌调频信号(CCFMS)的窄带延迟技术,利用混沌滤波同步实现了采用窄带延迟技术对宽带信号的延迟。根据CCFMS的动力学产生原理,构建了CCFMS的动力学同步响应模型。通过计算最大条件Lyapunov指数,探讨了系统同步对延迟性能的影响。与传统的延迟技术相比,这种窄带延迟技术能降低幅度相位不一致性及插入损耗,减小延迟设备代价,仿真结果表明了该技术可节省65%的延迟带宽。
A narrowband delay technique for continuous-chaos frequency-modulating signal（CCFMS） is proposed to realize broadband signal delay using narrowband delay techniques with chaotic filtered synchronization.Based on the dynamic generation principle of CCFMS,response system of dynamic model of CCFMS is constructed.And synchronization impact on delay performance is discussed by computing the maximum conditional Lyapunov exponent.Compared with the traditional delay techniques,this narrowband delay technique can reduce amplitude-phase uniformity,the insert loss and the cost of delay equipment.Simulation results show this technique can save the delay bandwidth by 65%.
