The echo of accelerating targets can be approximated as a linear frequency modulated signal which may degrades the MTD′s coherent integration performance.This paper presents an LFM detection method based on both discrete polynomial phase transform(DPT) and the fractional Fourier transform(FRFT).First,the interrelation between frequency resolution,cross-correlation delay,pulse length and integration performance of the classic DPT algorithm are analyzed.The result shows that detection performance of the DPT algorithm with a small time delay can be improved 3dB than classical algorithm.This is helpful to detect accelerating target under low SNR,but causes large parameter estimation error.Second,based on DPT algorithm,the FRFT is applied to further improve the accuracy of chirp rate estimation.When the input signal-to-noise ratio(SNR) is greater than-11 dB,one-dimensional Newton′s iteration method can help to improve the operation speed in the fractional domain.Finally,the algorithm complexity and the theory of estimation error are presented,and the validity of proposed algorithm is verified by simulation results which make the theory perfect.
