双稳随机共振在弱信号检测中的应用

Application of bi-stable stochastic resonance theory in weak signal detection

介绍了随机共振的基本原理,通过数值仿真研究了对称双稳系统的随机共振现象,并将其应用于微弱信号的检测,仿真结果证明了基于随机共振的微弱信号检测的有效性.

This paper introduced the basic principle of stochastic resonance （SR） and demonstrated SR phenomenon in symmetric hi-stable system by numerical simulation. Then, SR was applied to detect weak signal in a stronger noise background. The results obtained show the effectiveness of the detecting method based on SR.
