Abstract This paper introduces weak periodic pulse signal into given chaotic system, and uses the change of system phase track which leaps from chaotic status to periodic status as the detection criterion. The given chaotic system is used to realize weak periodic pulse signal detection under strong noise background. Simulation experiments show that chaos detection system is very sensitive to periodic pulse signal contained by strong noise and has strong constraint to any colored noise.
