Cover Story: A burst images sequence of the Sentinel-1B raw dataset was acquired through the terrain observation with progressive scan (TOPS) interferometric wide mode, processed using the phase-preserving focusing algorithm of TOPS synthetic aperture radar (SAR) data developed at IREA-CNR, Italy. The investigated raw data, acquired on 1 January 2019, include the Deutsche Zentrum für Luft-und Raumfahrt (DLR) calibration site, for a total extension of about 250 Km × 200 Km. The proposed algorithm consists of a first interpolation stage of the TOPS raw data, which allows unfolding the azimuth spectra of the TOPS raw data. Subsequently, the interpolated signals are processed using the conventional phase-preserving SAR focusing methods that exploit frequency domain and spectral analyses algorithms, extensively used to efficiently process Stripmap and ScanSAR data.
