N2 - SAR interferometry processing technology has developed for a few decades, and it is widely used in many geoscience applications. Nevertheless, conventional SAR interferometry processing methods do not suit for space-borne spotlight SAR interferometry processing. Based on co-registration with Doppler centroid frequency estimation and joint phase unwrapping method, a novel space-borne spotlight SAR interferometry processing method is proposed. It is validated by TerraSAR-X spotlight SAR data. Compared with SRTM data, the results show a clear improvement in DEM construction.
