Abstract

In this paper, we first demonstrate that the signal received from the laser underwater target detection system may be chaotic through phase space reconstruction, correlation dimension analysis and Lyapunov exponent calculation. Then the result of the correlation dimension analysis is used to construct a neural network predictor which is considered as an approximation of the basic dynamics of the received signal. Finally we introduce a chaos-based detection method and apply it to detect the underwater target. The performance of this new method is superior to that of the conventional method.
