Uninhabited Aerial Vehicle Synthetic Aperture Radar

The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, is an imaging radar instrument that collects key measurements of Earth deformation. When flown over the same area multiple times, it can determine how land features have changed. So far, it has been put to work studying climate change in the Arctic and examining Earth deformation after major earthquakes and volcanoes.

Originally designed to fly on an uninhabited aerial vehicle, the instrument currently flies aboard a NASA Gulfstream III aircraft.
