摘要：Aiming at the difficult problem of weak signal detection, a weak signal detection method based on the compound system for weak signal with unknown frequency is proposed, which implements the detection of weak signal submerged in strong noise and provides for the basic theory and technical support for the protection of industrial processes to efficient and stable operation, using the sensitivity of the state transitions of the phase trajectories of the system (from the chaotic state to the large-scale periodic state) to the weak signal input, combining with the filter capability of the correlation method.
