![]() Unlike earlier missions, SRTM will use single-pass interferometry, which means that the two images will be acquired at the same time - one from the radar antennas in the shuttle's payload bay, the other from the radar antennas at the end of a 60-meter (200-foot) mast extending from the shuttle. Successful completion of the SRTMĭata set will provide NIMA with coverage of most of Earth's populated landĪreas, with three times better resolution than previously available.Ī key SRTM technology is radar interferometry, which compares two radar images taken at slightly different locations to obtain elevation or surface-change information. The 11-day SRTM flight will yield enough data for a digital model of Earth that is more detailed than what is currently available. User requirements and provide worldwide DTED coverage. Process IFSAR and develop data sets that satisfy improved This effort should result in a NIMA production capability to Methodologies for on-site validation and processing of raw The IFSAR program within NIMA is investigatingĬharacteristics of IFSAR elevation data along with The Shuttle Radar Topography Mission is a joint project of the National Imagery and Mapping Agency (NIMA) and the National Aeronautics and Space Administration (NASA) to map the world in three dimensions. The main source of these data willīe the Shuttle Radar Topography Mission (SRTM), which isĪn IFSAR mission to be flown aboard the Space Shuttle in High-resolution elevation data produced through a techniqueĬalled radar interferometry. Program represents an effort to ingest and process The Interferometric Synthetic Aperture Radar (IFSAR) Interferometric Synthetic Aperture Radar (IFSAR)
