Sentinel 1B was lanched on 25th April 2016 and provides continuous all-weather, day and night imaging radar data. The IW mode is the main operational mode. The IW mode supports single (HH or VV) and dual (HH+HV or VV+VH) polarisation. \r\n\r\nThe IW SLC product contains one image per sub-swath, per polarisation channel, for a total of three or six images. Each sub-swath image consists of a series of bursts, where each burst was processed as a separate SLC image. The individually focused complex burst images are included, in azimuth-time order, into a single sub-swath image, with black-fill demarcation in between\r\n\r\nUnlike SM and WV SLC products, which are sampled at the natural pixel spacing, the images for all bursts in all sub-swaths of an IW SLC product are re-sampled to a common pixel spacing grid in range and azimuth. The resampling to a common grid eliminates the need for further interpolation in case, in later processing stages, the bursts are merged to create a contiguous ground range, detected image.\r\n\r\n\r\nThese data are available via CEDA to any registered user.","keywords":"Sentinel, radar, Synthetic Aperture Radar, SAR, Interferometric Wide, IW, Single Look Complex, SLC","publicationState":"published","dataPublishedTime":"2021-06-29T12:23:40","doiPublishedTime":null,"updateFrequency":"asNeeded","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/32810/?format=json","dataPath":"/neodc/sentinel1b/data/IW/L1_SLC/IPF_v3/","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":1514497644380227,"numberOfFiles":1834079,"fileFormat":"Image data files are in a binary format.
