Oboard Radar Processor of SOSTAR-X

The SOSTAR-X system is an advanced airborne ground surveillance radar system. This multi-mode radar demonstrator allows the acquisition of highly squinted and long range data in several SAR, Classification and MTI modes, as well as in simultaneous SAR/MTI modes. Furthermore, tracking functionalities are included. The radar raw data are processed onboard the aircraft on a real-time Radar Processor. The Radar Processor development was shared between the SOSTAR-X companies Dutch Space (NL), EADS (DE), Galileo Avionica (IT), Indra Sistemas (ES) and Thales (FR). Flight trials on a Fokker F100 aircraft were performed in 2006 and 2007. This paper presents the architecture of the SOSTAR-X Radar Processor and some spotlight SAR processing results from the flight trials.
