Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), a Jet Propulsion Laboratory (JPL)-built reconfigurable, polarimetric L-band synthetic aperture radar (SAR), is specifically designed to acquire airborne repeat-track SAR data for differential interferometric measurements.

The radar is designed to be operable on a UAV (Uninhabited Aerial Vehicle) but will initially be demonstrated on a NASA Gulfstream III. The radar is fully polarimetric, with a range bandwidth of 80 MHz (2-m range resolution) and a range swath greater than 16 km.

Open access — no proposal is required.
