SRTM C-BAND RADAR  

Definition

  • The Shuttle Radar Topography Mission (SRTM) collected topographic data of the Earth aboard the space shuttle Endeavour during its STS-99 mission which was flown February 11 through 22, 2000. The mission was an international project designed to generate a near-global digital elevation model (DEM) of the Earth using radar interferometry. SRTM utilized single-pass interferometry which compared two radar signals taken at different angles. The C-band antennas transmitted and received radar at a wavelength of 5.6 centimeters. One antenna was located in the shuttle's payload bay, and the other on the end of a 60-meter (200-foot) mast that extended from the payload pay once the Shuttle was in space. SRTM collected C-band radar data in swaths, with a swath width (width of the radar beam on Earth's surface) of 225 kilometers (km) from an altitude of 233 km. The C-band radar acquired during the mission was processed by the National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA). Endeavour orbited Earth 16 times each day during the 11-day mission, completing 176 orbits. SRTM successfully collected radar data over 80 percent of the Earth's land surface between 60° North and 56° South latitude. The C-band data were processed at the Jet Propulsion Laboratory to make a near-global topographic map of the Earth. (en)
