Study on the method of intermittent chaos to detect the weak signal

摘要

In this paper, we use the largest Lyapunov exponent proved that Duffing oscillators system have the immune to arbitrary distribution with zero-mean noise. For the unknown signal, we can use intermittent chaos to realize signal detection. Through experiment simulation, we use the least number of chaotic oscillator array to realize the signal frequency detection. Simulation experiments show that this method is simple, effective, high detection precision.
