definition: Shuttle Imaging Radar-B (SIR-B) is an horizontally polarized L-band radar operating at frequency 1.28 GHz (wavelength 23 cm). The SIR-B antenna had the capability of being mechanically tilted to acquire data at varying incidence angles from 15 to 60 degrees. The SIR-B obtained imagery at a resolution of approximately 25 m (varying with incidence angles) with a swath width of 20-50 km. The SIR-B provided both digitally recorded and optically recorded data. Additional information available at "http://southport.jpl.nasa.gov/scienceapps/sirb.html" [Summary provided by NASA]
