Abstract

At the University of Hannover a fully programmable DSP, the HiPAR-DSP 16, was developed. This HiPAR-DSP 16 contains 16 parallel datapaths and a 2-dimensional memory adapted to image processing algorithms. For real time SAR processing high computational power is required. Therefore a multi DSP board with 6 HiPAR-DSP 16 is developed. The high performance of up to 28 GOPS enables a SAR processing in real time. The calculation time for the ωκ-algorithm running on this board was estimated. For blocks of 4096 lines with 4096 8 bit complex samples real time processing is possible to a pulse repetition frequency (PRF) of 1200 Hz. Due to a low power consumption and the small size of 160×230 mm² of this board the use in on-board systems is predestinated.
