Research on Underwater Signal Processing Methods.

      Аннотация: This book systematically introduced the chaos theory and current weak signals detection methods and its basic principles based on chaos theory. After analysis and study the chaotic system of Duffing oscillator in depth, it was applied to detect the periodic weak signals within background noise. Since the neural network has the ability of parallel calculation, self-orgnization, self-learning and overall approaching along with the short-term predictablility of chaos.
