AbstractThe new airborne synthetic aperture radar (SAR) system developed for the Canada Centre for Remote Sensing is described. It consists of two radars at C and X-Bands. Each radar incorporates dual-channel receivers and dual-polarized antennas; a high quality, 7-look, RealTime processor; a sensitivity time control for range dependent gain control; a motion compensation system for antenna steering in azimuth and elevation, and baseband I and Q signal phase rotation. The system also features a high power transmitter with a low power backup. It maps to either side of the aircraft, at high (5.6 m slant range, 6 m azimuth) or low (20 m slant range, 10 m azimuth) resolution, at incidence angles which in high resolution span 0° to 80°. In the higher resolution mode, the slant range swath width is 16.4 km; while it is 63 km for the lower resolution, wide swath mode, with 4096 range cells in each case. This paper briefly describes the radar operating parameters, data products, key specifications and the motion compensation scheme used. Properties of the RealTime imagery are discussed and examples of C-Band SAR data in the three operating modes are presented.
