3.4 Deburst
The Terrain Observation with Progressive Scanning SAR (TOPSAR) in IW mode product acquires single image per swath per polarization mode(Keydel, 2007). Each IW product has three swath and acquisition is done in sub-swaths with successive burst series(Tripathi, Kumar, & Maithani, 2018). This step is used to compensate for the pixel spacings in both range and azimuth direction for better acquisition and sub-swath synchronisation(Hoa et al., 2019).
