Doppler Compensation for Phase-Coded Signals
相位编码信号的多普勒补偿

Phase-coded signals suffer from Doppler mismatch in pulse compression due to the characteristics of the ideal thumbtack ambiguity function. In this paper, a novel model of measuring velocity-and-range and the corresponding Doppler compensation algorithm from the perspective of 2D image reconstruction are described considering of the intra-pulse Doppler. Simulation shows that the proposed method solves the Doppler-mismatch problem and obtains the satisfactory compression result when velocity ambiguity and range migration are taken into account.
