Abstract :
This paper presents a study of the use of PVM (parallel virtual machine) to improve the speed of synthetic aperture radar (SAR) image processing. PVM is a software system that enables a user-configurable pool of heterogeneous computers to be used as a virtual machine. The SAR processing test software performed simplified range and azimuth compression on simulated SAR images of a point target. Results show that PVM improves the time taken to process a SAR image once system factors are optimised
