摘要
Abstract
Duffing oscillator has proved to be a chaotic system which is sensitive to particular weak sinusoidal signal and insensitive to white noise .By introducing the signal as the input of the Duffing oscillator and then observing the change of the state portrait ,this characteristic can be used to detect weak sinusoidal signal under strong noise background .Mix program-ming with LabVIEW and Matlab /Simulink can not only create communication between each other but also have complementa-ry advantages .Realizing chaotic weak signal detection by applying LabVIEW Simulation Interface Toolkit ,the accuracy can be achieved up to - 143dB ,with the interface more friendly and easier to operate .关键词
