Phase calibration of an along-track interferometric FMCW SAR
IEEE Trans. Geoscience and Remote Sensing（2018）
摘要
Techniques to estimate and correct range-dependent phase differences between receivers in an FMCW ATI SAR are studied. Both techniques reproduce the range-dependent phase ripple seem in the ATI interferograms.
