Abstract:

A theory is presented which enables the computation to be made of 200- to 5000-cps bottom reverberation returning from very great ranges in shallow-water. Typical computed curves are presented for reverberation level vs rangewater-depth. Computed curves are presented for scattering strength vs rangewater-depth. These later curves are presented for both the isospeed and negative sound-speed gradient cases. Author
