Crater <a href="https://en.wikipedia.org/wiki/Menrva" class="extiw" title="en:Menrva">Menrva</a> on Titan: comparing of 2 radar images, made by <a href="https://en.wikipedia.org/wiki/Cassini%E2%80%93Huygens" class="extiw" title="en:Cassini–Huygens">Cassini</a> spacecraft. The bigger image was made 20 June 2011 (during T77 flyby); strip, running from the left to the right, was made 15 February 2005 (flyby T3). Differences between the images are result of different incidence angle of radar beam, different distance to the target and different way of locating (<i>SAR</i> in T3 and <i>HiSAR</i> in T77). Image width is about 1130 km (1.4 km in a pixel).
North is up. The animation was obtained by transforming of radar image <a rel="nofollow" class="external text" href="http://pirlwww.lpl.arizona.edu/~perry/RADAR#T3">T3</a> to <a href="https://en.wikipedia.org/wiki/equirectangular_projection" class="extiw" title="en:equirectangular projection">equirectangular projection</a> according to <a rel="nofollow" class="external text" href="https://planetarynames.wr.usgs.gov/images/Titan_comp_ISSimage.pdf">IAU map of Titan</a>; then image <a rel="nofollow" class="external text" href="http://pirlwww.lpl.arizona.edu/~perry/RADAR#T77">T77</a> was aligned to it.
