The Judgment of Chaotic Detection System's State Based on the Lyapunov Exponent

Abstract

In order to improve the accuracy of the judgment of chaotic detection system's state, the Lyapunov exponent was used for judging the state of the chaotic detection system in this paper. With the method the system's state can be quantitatively judged, and based on the method this paper carried out the system simulation and the data analysis. Proved by the experiment result, it is feasible that uses Lyapunov exponent to judge the state of the chaotic detection system, which therefore can be availably used on the weak signal detection and then ensure the reliability of the signal detection.
