Radar geomorphologic characterization of Titan

Titan is one of Saturn´s moons and is characterized by the presence of a dense atmosphere, opaque for optical sensors. Therefore radar is the only method theoretically capable of giving relatively detailed information about the surface structure of Titan. Some possible Titan models have been considered and the radar requirements to meet the scientific objectives have been established. In order to estimate the composition of the surface and the presence of an ocean if any, particular attention was devoted to the coherent scattering model. By considering a proper extension of the ocean, the obtained models can partially justify the apparent disagreement between the ground based radar observations and the available model of Titan
