Research on Detection of Hypersonic Weak Target

摘要：

For the problem of range migration due to fast moving of the target, a novel coherent integration method based on Fractional Fourier transform（FRFT）is presented. Using the scale transform character of FRFT, the proposed method can accomplish scale transform at the same time of coherent integration, which can correct range migration, and all pulses can achieve effective accumulation in accumulation time. As a result, it is proved that this method improves the detection performance of hypersonic target greatly, and reduces the demand of the input SNR.
