A compact real-time SAR processing system using the highly parallel HiPAR-DSP 16

At the Laboratorium fu/spl uml/r Informationstechnologie the HiPAR-DSP 16, a parallel digital signal processor (DSP) optimized for image processing algorithms, has been developed. We present a design of a compact multi-DSP board utilizing the HiPAR-DSP 16. Two boards were implemented: an application development board with a PCI interface and a board for SAR processing. With a computational power of up to 15 GOPS this board is suitable for real-time SAR processing, as an estimation for an /spl omega/k algorithm (range line length of 4096 samples, PRF of 600) shows. A volume of 160/spl times/230/spl times/20 mm/sup 3/ and a power consumption of less than 20 W enables on-board integration. The first version of the board is used for filtering of SAR data to show the capabilities of the system.
