The GeoSAR airborne mapping system

This paper provides an overview of the GeoSAR radar hardware and processor structure. An example DEM is also shown to demonstrate the capability of the X-band radar. This imaging system was designed to be a robust and automated mapping system. Test flights are flown to verify the flight planning software and the automatic radar controller that automates the radar operations. Phase III of the project includes the completion of instrument testing, automation and calibration, system level analysis of phase unwrapping and motion compensation effects on terrain mapping performance, and long wavelength foliage penetration studies
