In this paper, we describe the process of parallelizing an existing, production level, sequential
Synthetic Aperture Radar
(SAR) processor based on the Range-Doppler algorithmic approach. We show how, taking into account the constraints imposed by the
software architecture
and related
software engineering
costs, it is still possible with a moderate programming effort to parallelize the software and present an message-passing interface (MPI) implementation whose speedup is about 8 on 9 processors, achieving near real-time processing of raw SAR data even on a moderately aged parallel platform. Moreover, we discuss a hybrid two-level parallelization approach that involves the use of both MPI and OpenMP. We also present GridStore, a novel
data grid
service to manage raw, focused and post-processed SAR data in a grid environment. Indeed, another aim of this work is to show how the processed data can be made available in a grid environment to a wide scientific community, through the adoption of a
data grid
service providing both metadata and
data management
functionalities. In this way, along with near real-time processing of SAR images, we provide a data grid-oriented system for data storing, publishing, management, etc.
