Topographic Synthetic Aperture Radar is an aircraft radar interferometer that uses radar and interferometry to rapidly produce topographic maps of Earth. TOPSAR operates a C-band (6-cm-wavelength) radar interferometer as an adjunct to the AIRSAR instrument on board a NASA DC-8 aircraft. It uses two antennas mounted nearly vertically on the left side of the aircraft. Interferometric maps of Earth's surface are constructed by comparing the phase differences between radar images from the two antennas. TOPSAR is a precursor to a possible satellite system that could produce a global digital topographic map.
