SIR-C/X-SAR observations of soil moisture over the CCRS Altona, Manitoba test site

Since the late 1970s a variety of satellite missions have used imaging radar to study the Earth. The joint U.S./German/Italian Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) is the next step in that program. SIR-C/X-SAR flew aboard the space shuttle Endeavour in April and October 1994 as part of the Space Radar Laboratory (SRL). This paper describes the SIR-C/X-SAR data acquisition over the CCRS Altona, Manitoba test site. In addition to the SIR-C instrument, data were also acquired by the JPL AIRSAR operating at C-, L-and P-Band and the CCRS CV-580 operating at C- and X-Band
