Retrieval of high-resolution topography of the Titan’ surface by using Cassini SAR data

Gathering reliable information about the topographic context greatly enhances the readability and interpretation of Cassini synthetic aperture radar (SAR) data, and allows for a better understanding of the overall Titan satellite. The Cassini Titan Radar Mapper has observed several morphological structures, such as dunes, lakes, craters and river-like channels [1] . In addition, regions exhibiting relatively high topography, referred to as mountains, have been discovered and analyzed [2] . Since the beginning of the mission in 2004, different methods have been developed to retrieve Titan’s topography using Cassini RADAR, e.g., SARtopo, altimetry, stereophotogrammetry [1] – [5] . An updated complete topographic map of Titan’ surface obtained by combining and interpolating all the available data has been recently presented in [4] .
