The stochastic resonance in Bistable Duffing System is studied in this paper. For the large parameter condition which does not meet the adiabatic approximation, a kind of adaptive stochastic resonance weak signal detection system based on frequency control is proposed in this paper. It can detect the unknown high frequency weak signal. The simulation results show that the system can realize high frequency signal stochastic resonance. Compared with the traditional stochastic resonance system, its precision and system output signal-to-noise ratio is greatly improved, and its application in the weak signal detection field is extended.
