UAVSAR Technical Specifics

The radar for the UAV platform is a compact, pod-mounted, polarimetric L-band radar for repeat-pass observations. The system will demonstrate key measurements — both during and after a seismic event — for monitoring volcanic activity and for monitoring anthropogenic induced surface change such as subsidence induced by oil or water withdrawal, or other displacements of the surface from tunneling activities.

UAVSAR Summary

UAVSAR 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.
