AB: During the first 15 months of the Cassini Saturn Tour, the Cassini RADAR instrument has conducted a number of observations in both active and passive modes. Data from four Titan flybys, seven distant Titan observations, eight distant icy satellite observations, three sets of microwave source scans, and four engineering tests were collected. The Titan flybys provide relatively high resolution (500 m) synthetic aperture radar images, while the distant scatterometer observations provide disk integrated backscatter from Titan and the other icy satellites in the Saturn system. The engineering tests and microwave source scans provide specialized data about how the radar system is performing. Calibrating the various operating modes of the Cassini RADAR is an ongoing, challenging task. In this paper we will examine the status of the current radar and radiometer calibration using the available data. We will discuss these results and future plans to improve absolute and relative calibration of brightness temperatures and radar backscattering cross-sections.
