A high performance digital signal processor for compact realization of real-time synthetic aperture radar systems

Modern SAR applications have a large amount of needed processing power. Most of the currently available architectures lack of flexibility or performance. In this paper a new parallel and programmable architecture for image processing applications is described. The presented HiPAR-DSP is able to serve the requested demands, like providing the high performance as a dedicated architecture and still having the flexibility of a fully programmable processor. The implementation of the range compression shows a real-time capability of processing up to 1500 rangelines with 4096 complex samples with the HiPAR-DSP.
