Synthetic aperture radar altimeter
WebThe primary payload of the mission is a synthetic aperture radar Interferometric Radar Altimeter (SIRAL), which measures surface elevation. By subtracting the difference between the surface height of the ocean and the surface height of sea ice, the sea ice freeboard (the portion of ice floating above the sea surface) can be calculated. WebInverse Synthetic Aperture Radar operates under the same basic principle but with one key difference: ISAR uses the movement of the target itself to generate its reading, rather than …
