1) The document describes a bistatic synthetic aperture radar (SAR) system using TerraSAR-X satellites and a ground-based receiver called SABRINA-X. 2) SABRINA-X was designed as a low-cost, multi-channel receiver to receive signals scattered from the illuminated area as well as direct signals from the satellite. 3) Initial results using SABRINA-X to receive signals from TerraSAR-X demonstrated the ability to generate bistatic SAR images and interferograms of the Barcelona harbor area. Accurate calibration of receiver channels was important for good results.
