DOI: 10.1109/jstars.2022.3204539
Abstract: In synthetic aperture radar (SAR), due to the characteristics of squint data in spaceborne imaging geometry, a more accurate range cell migration correction operation is necessary. Furthermore, imaging degradation due to ignoring range-variant filtering needed… read more here.
