AB: From July 2004 through July 2008, the Cassini spacecraft will be conducting an extensive survey of the Saturn system with many instruments. The Cassini RADAR instrument will collect data in both active and passive modes providing co-polarized backscattering cross-sections and brightness temperatures. These data will be obtained for Titan at close range and relatively high resolution (500 m), and for several of the icy satellites at longer range with low (whole disk) resolution. Passive data will also be collected on the Saturn disk and the ring system. Calibrating the various operating modes of the Cassini RADAR will be an important and challenging task during the Saturn Tour. This paper will discuss the procedures and observations being planned to address absolute and relative calibration of the Cassini RADAR active and passive data sets. The first few observations will provide some data on the performance of these calibration procedures. We will discuss these results and the implied limits on the ultimate accuracy of brightness temperatures and backscattering cross-sections.
