Chaos-based weak sinusoidal signal detection approach under colored noise background

In this paper we consider a new weak signal detection scheme which uses the sensitivity of chaos to the parameters under a certain status to realize weak signal detection. This scheme can effectively extract the weak sinusoidal signal from the strong colored noise background. We present a chaos-based signal detection approach, analyze the influence of noise to the system status in the chaos detection process. Simulation experiments show that the chaos detection system is very sensitive to weak signal and have strong constraint to any colored noise with zero mean value.
