Abstract :
In this paper, the authors introduce a signal detection scheme based on the bifurcation behavior of the driven Duffing oscillator. Chaotic systems are sensitive to certain signals and immune to noise at the same time, the properties of which demonstrate their potential application in weak signal detection. Starting from the analysis of the intermittent chaotic motion occurring in the detecting process, they put forward a new frequency-locking principle based on the periodic characteristic of the intermittent chaos. Then, an exposition is made on how to use an array of the oscillators to detect the weak signals of unknown frequency
