Real time MTI STAP first results from SOSTAR-X flight trials

This paper presents the achievements of the flight campaign of the SOSTAR-X (Stand-Off Surveillance and Target Acquisition Radar) program relevant to the Ground Moving Target Indicator (GMTI) modes designed for Wide Area Surveillance and Fast Sector Scan. The SOSTAR-X is the European technologic demonstrator for an advanced AESA (Active Electronically Steered Antenna) airborne radar sensor. This program can be considered as the first European Consortium adventure for this kind of radar. It completed formal acceptance flight tests on July 2007, demonstrating on the field the fulfilment of all the main performance requirements. Some considerations are also addressed about the main issues to be investigated with the use of real data.
