Acoustic phase measurements from volume scatter in the ocean

A primary goal of this thesis has been to demonstrate that stable, useful
measurements of the orientation of the acoustic signal vector as a function of
range and time can be obtained from ocean backscatter, and that this orientation,
or acoustic phase, can be related to the local sound speed distribution.
Such a measurement is quite distinct from the related problem of detecting the
rate of phase change, which forms the basis of Doppler technology. Doppler
measurements can be made using echoes from a single point, or a sparsely
distributed set of targets. Consistent and useful measurement of absolute phase,
is inherently more difficult, since it depends upon the positions of individual scatterers, which are normally random and sparse relative to the acoustic
wavelength. / Graduate
