摘　　要：本文对混沌时间序列的线性滤波特性进行了深入研究,将经典的匹配滤波技术与混沌时间序列的局部预测方法相结合,提出了混沌、噪声背景中信号检测的新方法。最后,用典型的混沌系统的具体分析验证了本文方法的正确性和有效性。In this paper, the linear filtering nature of the chaotic time series is studied thor-oughly and the new signal-detection method in chaos and noise is developed in which the local predicted method of the chaotic time series is combined with the matching filter. Finally, by means of specific analysis of some prevailing chaos systems the correctness and effectiveness of this method are testified.
