In this paper, a novel intra-pulse modulation phase calibration with a two-dimensional (2-D) parametric phase model is proposed.  ...  It models the intra-pulse phase errors as a 2-D time-variant polynomial with accommodation of both fast-time and slow-time modulation.  ...  ACKNOWLEDGMENT The authors would like to thank the anonymous reviewers for their enlightening comments and carefully review.  ...
