C-BAND RADAR  

Definition

  • C-band radar has a nominal frequency range from 8 to 4 Ghz (3.75 to 7.5 cm wavelength) within the microwave (radar) portion of the electromagnetic spectrum. The corresponding wavelength for these systems is on the order of 5.6 cm, which has been found useful in sea ice surveillance as well as in other applications. Imaging radars equipped with C-band are generally not hindered by atmospheric effects and are capable of 'seeing' through tropical clouds and rain showers. Its penetration capability with regard to vegetation canopies or soils is limited and is restricted to the top layers. C-band is also used in range instrumentation radars. (en)

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. language code: en);
