On-board Processing Architecture of DLR’s DBFSAR / V-SAR System

Inhalt:
For real-time Synthetic Aperture Radar applications, data must be processed and sent to the ground station efficiently. This paper describes the processing architecture of DLR’s DBFSAR system with the aim of presenting recent developments of on-board radar processing. It explains how the low level optimizations were conducted and under which conditions their integration in the SAR imaging process and maritime moving target indication leads to real-time capability.
