Abstract:

With the exception of those cases where sound channels exist, the transmission of underwater sound to extreme ranges is possible in most cases only because much of the energy which strikes the ocean bottom is reflected back into the water. In many cases several successive reflections from surface and bottom may occur before the sound wave finally reaches the receiver. Thus, an understanding of the bottom reflection phenomena is important. This study is concerned chiefly with those signals which have experienced only a single reflection from the ocean bottom, and possibly one or two reflections from the surface. However, signals experiencing any number of reflections may be handled in a similar manner. Author
