The Study of Weak Signal Detection Based on Chaotic Oscillator

摘要

in this paper, the dynamic character of Duffing equation is analyzed. It is immune against the white noise and the interference signal having larger frequency difference with the intrinsic frequency of chaotic oscillator. This character of chaotic oscillator is used in weak signal detection. The author gives a new method, which the detection signal is used as the motive power absolutely and the frequency of detection signal is gotten with oscillator array method. The simulation experiment is included that it is easy and efficiency.
