Abstract

Abstract: Because the chaotic oscillator can detect signal under lower SNR than the usual signal detection methods, it has been widely studied. In order to extend the application range of the existing chaotic oscillator to aperiodic pulse signal detection, a detection method based on dual Duffing oscillator is proposed. The method uses the difference between the state variables of two generalized time scale Duffing oscillators to detect signal. By selecting the system parameters rationally, the method can detect aperiodic square pulse while the SNR is as low as -30 dB, and detect signals at lower SNR than existing methods. Simulation results show that the method can be applied to signal detection in a wide range of signal sampling frequency and a wide range of signal amplitude.
