First Experimental SCAN / MTI Results Achieved With the Multi-Channel SAR-System PAMIR

The airborne experimental SAR system PAMIR has been conceiv ed by FGAN-FHR in order to demonstrate some features of future reconnaissance systems. Since 2003, the new SCAN/ MTI mode has been implemented and experimentally tested. This mode provides a significant improvement to the u sual MTI mode with fixed beam, since the antenna is regularly steered to different azimuth angles, allowing to scan much larger scenes. Some specific algorithms are curren tly under development in order to process the SCAN/MTI data gath ered during the flight campaign of November 2003. This paper presents the first SCAN/MTI results achieved with the P AMIR system. After a description of PAMIR, the flight experiment is outlin ed. Then an overview of the SCAN/MTI signal processing is given. Finally some first results are shown.
