A shallow water system for maximizing echo to reverberation ratio
Williams, Robert Bruce (NATO. SACLANTCEN, 1993/08)A method for increasing incident energy on mid-depth targets while at the same range reducing boundary reverberation for shallow water ducts has been devised. The basis of the approach is couched in range dependant normal ... -
Gas bubbles in the sea: a review and model proposals
Williams, Robert Bruce; Foster, Leslie A. (NATO. SACLANTCEN, 1975/10)The literature pertaining to both free bubbles (pt 1) and bubbles associated with fish anotomy (pt 2) is reviewed with particular emphasis on their distributions in the sea and influencing factors. An attempt is made to ... -
Highlights of bottom topography inferred from received depression and bearing angles
Phelan, F. M.; Williams, Robert Bruce; Fisher, F. H. (NATO. SACLANTCEN, 1975/10)Statistical properties of the acoustic reflection from the ocean floor have been studied for a var i.ety of bottom types including deep, smooth, flat topography thorough, jagged bottom in shallower (~l km) depths. Explosive ... -
