摘要：

Based on Fractional Fourier Transform (FrFT), a targets number detection method is proposed for conventional narrow-band radar in this paper. Firstly, the fractional Fourier transform angle is estimated based on the minimum entropy criterion. And then, the narrow-band echo data are transformed to frequency domain via FrFT from the estimated angle. Finally, the sorties are identified by peak detection of the transform results. The simulation results verify the effectiveness of the proposed method.
