| 摘 要： | 从工程中经常碰到的噪声背景下弱信号检测的实际需求出发，提出一种基于线性系统随机共振的弱信号检测方法，与传统的非线性系统随机共振相比，此方法计算量小、检测速度快。采用MATLAB配用的SIMULINK软件，建立线性系统随机共振仿真模拟图，通过调节系统参数或噪声强度，使系统噪声及激励信号达到最佳匹配，从而实现弱信号的检测。仿真结果表明该方法具有可行性。

| Abstract: | Articles from engineering noise often encountered in the context of the actual needs of the weak signal detection,so this paper proposes a linear system based on stochastic resonance in weak signal detection methods.Compared with the traditional stochastic resonance of nonlinear systems,the method has a small amount of testing speed.Articles uss MATLAB with SIMULINK software used in the establishment of stochastic resonance in linear system simulation diagram,by adjusting the system parameters or noise inte... |
