Abstract Firstly, the characteristic of Duffing oscillator is studied, and based on the combination of Duffing oscillator with wavelet transform and neural network, a new detection method for low speed and small target over noise background is proposed. The simulation results show that the proposed method succeeds in detecting low speed target with low false alarm probability in low signal to noise ratio environment.
