On October 5, 1984, the space shuttle Challenger carried the Shuttle Imaging Radar-B, developed and built by the Jet Propulsion Laboratory (JPL), into orbit as part of the OSTA-3 (Office of Space and Terestrial Applications) payload. During its eight-day mission, SIR-B gathered digital radar imagery covering 5 million square kilometers of the earth's surface between 57 deg north and south latitudes. Of major concern was the collection of radar imagery of the same target at different incidence angles, creating a means of classifying surfaces by their backscatter response as a function of incidence angle. Chosen by NASA to work with the data were 43 scientists representing academic, private and government interests from around the world. Study areas spanned the fields of geology, archeology, forestry, agriculture, oceanography, geography and hydrology. In spite of transmitted power problems experienced during the mission, useful imagery was obtained for all of the above interests, substantially contributing to spaceborne multiple incidence angle radar studies.
