| Description |
Русский: Кратер Менрва на Титане: сравнение двух радарных снимков, сделанных аппаратом «Кассини». Основа изображения — снимок, сделанный 20 июня 2011 (во время пролёта T77); наложенная полоска, проходящая слева направо — снимок, сделанный 15 февраля 2005 (во время пролёта T3). Снимки отличаются из-за разного направления радарного луча, разного расстояния до объекта и разных методов радиолокации (SAR в случае T3 and HiSAR в случае T77). Ширина изображения — около 1130 км (в 1 пикселе 1,4 км).
Север сверху. Картинка получена приведением радарного снимка T3 к равнопромежуточной проекции согласно карте МАС и наложением на него соответственно трансформированного снимка T77. English: Crater Menrva on Titan: comparing of 2 radar images, made by Cassini 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 (SAR in T3 and HiSAR 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 T3 to equirectangular projection according to IAU map of Titan; then image T77 was aligned to it. |
