Computer models for underwater sound propagation
(NATO. SACLANTCEN, 1975/10)
The state of affairs of computer models for underwater sound propagation loss estimation is discussed from the viewpoints of two segments of the sonar community; i.e., (1) those who develop the models and are primarily ...
Ocean-bottom reflectivity (a point of view)
(NATO. SACLANTCEN, 1975/10)
The analysis procedures for extracting bottom loss values from pulsed acoustic signals that have interacted with the ocean bottom do not inherently consider sub-bottom refraction and reflection of sound, which are important ...
