ACOUSTIC REVERBERATION AT THE SEA SURFACE: SURFACE AND SUBLAYER SPECTRA VIS-A-VIS SCATTERING AND REFLECTION
2006
Martin, John J.
On the basis of theoretical estimates of acoustic scattering and reflection strengths of rough surfaces and turbulent volumes, acoustic and optical data are interpreted so as to develop, on the one hand, spectra of sea surface roughness and of the turbulent sea subsurface layer and, on the other, an acoustic reverberation strength correlation formula. The range of application of both of these is for wind speeds up to about 20 knots (about 10 m/sec); the spectra range between 0.05 and 5 radians/cm, and the acoustic reverberation strength correlation formula applies between acoustic frequencies of 0.6 kcps and 60 kcps.
