The Synthetic Aperture Radar (SAR) is an active sensor widely used in remote sensing to obtain high resolution ground images from the back-scattered echo signals. When a digital processing is performed, a high computational load is involved and hw/sw solutions based on both specialized and general pupose machines can be exploited to speedup the image focusing algorithm. A more economical solution based on cluster of workstations is presented. The performance results of the version 1.0 of our distributed SAR processor achieved on a homogeneous cluster of IBM RISC System 6000/360 under PVM are reported.

Abstract
The Synthetic Aperture Radar (SAR) is an active sensor widely used in remote sensing to obtain high resolution ground images from the back-scattered echo signals. When a digital processing is performed, a high computational load is involved and hw/sw solutions based on both specialized and general pupose machines can be exploited to speedup the image focusing algorithm. A more economical solution based on cluster of workstations is presented. The performance results of the version 1.0 of our distributed SAR processor achieved on a homogeneous cluster of IBM RISC System 6000/360 under PVM are reported.File in questo prodotto:
