摘要
混响背景下目标信号的检测、降噪方法与实现,一直以来都是一个难题。建立了非线性降噪模型,并且应用此模型进行混沌时间序列信号检测。以典型的Henon混沌系统所产生的时间序列作为样本和水下目标信号噪声序列为例,进行了降噪和预测,结果表明该方法是有效的,可行的。
The method for detection , denoise and realization of signals in chaotic background is difficult. A new model of nonlinear denoise is proposed and applied in the detection of chaotic time series signals. As an example of denoise, classic chaotic Henon time series and the noise series of the target signals under water are used to denoise and predicted. The results illuminate that the method is available and feasible.
