Abstract

This paper presents a Multi-DSP system for real-time SAR-processing using the HiPAR-DSP 16. We developed this full programmable processor at the Laboratorium für Informationstechnologie. With 16 parallel data paths and a two-dimensional memory it is optimized for image processing algorithms like FFT-transforms. SAR image synthesis methods, like the investigated ωk-algorithm, use the computational intensive FFT-transform. To overcome the large processing power of future realtime SAR image synthesis applications, several DSPs have to work in parallel. The presented compact SAR system can be easily adapted to match the demands of different SAR algorithms by scaling the number of processing nodes. Equiped with 6 HiPAR-DSP 16 a 233×175×15 mm3 board provides a realtime capability of processing SAR applications with a PRF of 1200 Hz. A rangeline length of 4096 8 bit complex samples and 4096 rangelines is assumed. The small volume and it's power consumption of less than 35 W enables it for on-board usage in compact air- or spaceborne systems.
