An algorithm based on Lyapunov exponents to determine the threshold of chaotic detection for weak signal

ZHANG Bin,LI Yue,MA Hai-tao(Jilin University, Changchun, 130012, China)  
An approach used to determine the critical threshold of the detection for weak signals is presented, that is the Lyapunov exponents is employed in the field of weak signal detection based on chaos, which provides a criteria for chaotic detection on quantity. An algorithm is applied to compute the Lyapunov exponents of the chaotic detection system, and is compared with other algorithms. Simulation results verify the validity and superiority of this algorithm.
