Geodetic Imaging with Interferometric Airborne Radar

Geodetic Imaging with Interferometric Airborne Radar Scott Hensley and Cathleen Jones Jet Propulsion Laboratory, California Institute of Technology 4800 Oak Grove Dr, Pasadena CA 91109. Unlike spaceborne sensors both revisit time and viewing geometry can be optimized to a particular application. Airborne sensors such as GeoSAR for topographic measurement and UAVSAR for deformation mapping are representative of the capabilities of airborne radar systems for making geodetically relevant measurements. We will provide a brief overview of the UAVSAR instrument and highlight the technical challenges in making airborne repeat pass measurements suitable for geodetic imaging. Several examples of geodetic imaging by UAVSAR will be presented showing the application or airborne repeat pass imaging to geodesy. The research described here was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
