Abstract
Coastal Systems Station has translated its synthetic aperture sonar beamformer from linear processing to parallel processing. The initial implementation included many linear processes delegated to individual processors and neglected algorithmic refinements available to parallel processing. The steps taken to achieve increased computational speed for real-time beam forming are presented.
