Abstract :
A weak signal detection technology based on stochastic resonance system is proposed in this paper. The principle of stochastic resonance is analyzed. Also a system based on Duffing equation is introduced. Then, a model is built using simulink soft ware. Finally, simulation is done using matlab software. Simulation results show that this technology can reach good test accuracy, against both white noise and colored noise.
