Further results from the SAMI synthetic aperture sonar

This paper presents two techniques which may enhance the usefulness of synthetic aperture sonar, specifically multi-ping and Vernier techniques. A more efficient method of synthetic aperture processing is introduced, which was useful in processing the Vernier data in real-time. Results from the sea-trials held in May 1996 are presented and the authors conclude that multi-ping and Vernier techniques have brought benefits to the SAMI synthetic aperture system.
