摘    要:该文将微弱周期脉冲信号引入特定的混沌系统中,以系统相轨迹由混沌状态到大尺度周期状态的跃迁作为微弱周期脉冲信号的检测依据,用特定的混沌系统实现了对强噪声背景下周期脉冲信号的检测。仿真实验表明该混沌检测系统对被强噪声覆盖的周期脉冲信号非常敏感,对任何色噪声均具有极强的抑制能力。

关 键 词:色噪声  混沌系统  信号检测  周期脉冲  信噪比  信号处理

Abstract:This paper introduces weak periodic pulse signal into given chaotic system, and uses the change of system phase track which leaps from chaotic status to periodic status as the detection criterion. The given chaotic system is used to realize weak periodic pulse signal detection under strong noise background. Simulation experiments show that chaos detection system is very sensitive to periodic pulse signal contained by strong noise and has strong constraint to any colored noise.
Keywords:Chaos system  Signal detection  Periodic pulse  SNR
