Abstract

The Cassini RADAR is a Ku band multimode instrument capable of providing topography information of Titan´s surface when operating in altimetry mode. During the last six years (January 2005 to 2011) Cassini has performed 71 Titan´s fly-bys and several observations have been collected in Altimetry mode. These profiles have shown Titan´s surface complexity. Along track profile resolution can be improved by processing data in a coherent approach. This paper describes an advanced processing applied to the raw Altimetric Cassini radar data (LBDR, Long Burst Data Record). The processing is based on the well known Doppler/Delay algorithm. Results show an improvement respect to the existing ABDR (Altimeter Burst Data Record) products in terms of along track resolution and SNR.
