UAVSAR- Uninhabited Aerial Vehicle Synthetic Aperture Radar

Thursday, May 7, 2015

The L-band radar aboard the AFRC G-III has embarked on a week-long deployment to the Louisiana Gulf Coast for coastal subsidence monitoring and a joint campaign with the AirSWOT radar at the Wax Lake Delta.  Scientists from JPL together with hydrologists from UT Austin and Rice University as well as ecologists from Louisiana State University have planned the Wax Lake Delta experiment to study sediment transport and delta formation.  They will use UAVSAR polarimetry for shallow water bathymetry and AirSWOT cross-track and along-track interferometry modes to study water level changes and surface velocity field respectively.  The UAVSAR and AirSWOT flights are coordinated with tidal conditions where they will acquire data at low tide, rising tide, and high tide.  There is an extensive ground campaign during the experiment where scientists will be taking measurements on the lake as well as in the wetlands.
