Kevin B. Smith
Professor of Physics
Associate Chair of Research
Ph.D. Applied Marine Physics, U. of Miami, 1991
Dr. Smith joined the faculty of NPS in 1995. His research interests include all aspects of underwater acoustic propagation, SONAR systems engineering and signal processing, as well as general improvements in acoustic modeling with the parabolic approximation as an aid to data analysis. Current research projects include experimental work with autonomous underwater gliders, studies of the physics and signal processing of the acoustic vector field, numerical studies of oceanographic variability on acoustic propagation, and the incorporation of rough surface scattering effects in a three-dimensional propagation PE model. Prof. Smith has advised/co-advised six Ph.D. students and more than 60 M.S. students. He is a Fellow of the Acoustical Society of America.
