The Cassini Titan Radar Mapper imaged about 1% of Titan's surface at a resolution of ∼0.5 kilometer, and larger areas of the globe in lower resolution modes. The images reveal a complex surface, with areas of low relief and a variety of geologic features suggestive of dome-like volcanic constructs, flows, and sinuous channels. The surface appears to be young, with few impact craters. Scattering and dielectric properties are consistent with porous ice or organics. Dark patches in the radar… Expand

Titan Radar Mapper observations from Cassini's T3 fly-by
Cassini's Titan Radar Mapper imaged the surface of Saturn's moon Titan on its February 2005 fly-by (denoted T3), collecting high-resolution synthetic-aperture radar and larger-scale radiometry andExpand
The Sand Seas of Titan: Cassini RADAR Observations of Longitudinal Dunes
TLDR
The most recent Cassini RADAR images of Titan show widespread regions that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth, and the distribution and orientation of the dunes support a model of fluctuating surface winds. Expand
Mapping products of Titan's surface
Remote sensing instruments aboard the Cassini spacecraft have been observed the surface of Titan globally in the infrared and radar wavelength ranges as well as locally by the Huygens instrumentsExpand
Titan's surface from reconciled Cassini microwave reflectivity and emissivity observations
Abstract The surface of Titan, Saturn's largest moon, appears to consist of solid hydrocarbons or CO2 with considerable small-scale structure, according to a new electromagnetic scattering model thatExpand
Cryovolcanic features on Titan's surface as revealed by the Cassini Titan Radar Mapper
Abstract The Cassini Titan Radar Mapper obtained Synthetic Aperture Radar images of Titan's surface during four fly-bys during the mission's first year. These images show that Titan's surface is veryExpand

Models of synthetic aperture radar backscattering for bright flows and dark spots on Titan
The synthetic aperture radar (SAR) imaging mode of the Cassini RADAR instrument enables us to map the surface of Titan through its thick atmosphere. The first Cassini close flyby, acquired on 26Expand
Ground processing of Cassini RADAR imagery of Titan
TLDR
The ground processing of Cassini SAR data focuses upon the unusual features of the data and how these features impact the processing, and a data dependent mechanism is exhibited for eliminating artifacts due to attitude and ephemeris knowledge error. Expand
Fluvial channels on Titan: Initial Cassini RADAR observations
Abstract Cassini radar images show a variety of fluvial channels on Titan's surface, often several hundreds of kilometers in length. Some (predominantly at low- and mid-latitude) are radar-bright andExpand
Mapping and interpretation of Sinlap crater on Titan using Cassini VIMS and RADAR data
[1] Only a few impact craters have been unambiguously detected on Titan by the Cassini-Huygens mission. Among these, Sinlap is the only one that has been observed both by the RADAR and VIMSExpand

Radar Evidence for Liquid Surfaces on Titan
TLDR
Arecibo radar observations of Titan indicate that most of the echo power is in a diffusely scattered component but that a small specular component is present for about 75% of the subearth locations observed. Expand
Imaging of Titan from the Cassini spacecraft
TLDR
Observations of Titan from the imaging science experiment onboard the Cassini spacecraft reveal intricate surface albedo features that suggest aeolian, tectonic and fluvial processes, and imply that substantial surface modification has occurred over Titan's history. Expand
