Bistatic ground-based passive SAR imaging using TerraSAR-X as an illuminator of opportunity

Abstract

The paper presents an experiment with bistatic passive SAR imaging in a scenario involving the TerraSAR-X satellite as an illuminator of opportunity and a static, ground-based receiver. The experiment was performed during a measurement campaign carried out by the Warsaw University of Technology in July 2012. In the paper the design of an X-Band receiver system and the bistatic SAR processing used for imaging are described. Also the resultant images produced for different polarizations of transmitted waves are included.
