Abstract:Recent synthetic aperture sonar (SAS) processing of low-frequency active acoustic data suggests that coherent integration apertures on the order of several thousand wavelengths can be achieved by using data-driven adaptive compensation techniques. This paper uses a normal mode based simulation to explore the interplay between adaptive compensation and medium coherence in SAS processing. Our analysis concentrates on signal fluctuations induced by background internal waves in a shallow-water region of the Medite… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
