                Title: "Radar: The Cassini Titan Radar Mapper"
                Publication: The Cassini-Huygens Mission, by Russell, Christopher T., ISBN 978-1-4020-3147-2. Kluwer Academic Publishers, 2004, p. 71
                DOI: 10.1007/1-4020-3874-7_2
                Abstract: The Cassini RADAR instrument is a multimode 13.8 GHz multiple-beam sensor that can operate as a synthetic-aperture radar (SAR) imager, altimeter, scatterometer, and radiometer. The principal objective of the RADAR is to map the surface of Titan. This will be done in the imaging, scatterometer, and radiometer modes. The RADAR altimeter data will provide information on relative elevations in selected areas. Surfaces of the Saturn's icy satellites will be explored utilizing the RADAR radiometer and scatterometer modes. Saturn's atmosphere and rings will be probed in the radiometer mode only. The instrument is a joint development by JPL/NASA and ASI. The RADAR design features significant autonomy and data compression capabilities. It is expected that the instrument will detect surfaces with backscatter coefficient as low as -40 dB.

                The CRT file documents the times of radar mode transitions.
                The file has been generated from the SBDR file in the DATA/SBDR
                directory of this volume.  For a detailed description of the CRT
                file format, refer to the Volume Software Interface Specification
                for Cassini Radar Instrument Team Data Products, which is located
                on this volume as file VOLSIS.PDF in the DOCUMENT directory.
