WebWhat is altimetry? Radar altimetry is an technique for measuring the height of an object or surface. In remote sensing, this is typically achieved by measuring the time it takes for a radar pulse, released by a satellite-based altimeter, to travel to a surface, reflect, and return to be recorded by an on-board detector. WebAltimeter data collected using satellites has been used to generate maps of 100 percent of the ocean bottom, at a resolution of 1.5 kilometers, or about one mile. While maps at this …
