N2 - In Pulsed Doppler radar, the phase-coded signal is used to achieve high range resolution profiles. When the target radial velocity is high, linear range migration occurs. It results in the degradation of a long-term coherent integration. A novel coherent integration method of coherent phase-coded pulse train is proposed based on Keystone transform. In order to reduce the computation complexity, the FT- IFT (Fourier transform - inverse Fourier transform) algorithm is presented for the implementation of Keystone transform. By using the proposed method, the detection sensitivity of weak targets is improved. Some computer simulation results are presented which illustrate the effectivity of the method.
