Title from cover
"15 November 1973"--Cover
"NPS-61MD73111A"--Cover
Author(s) subject terms: Sound fluctuations, ocean microstructure, upper ocean
Includes bibliographical references (p. 39-40)
Technical report; 15 November 1973
The temporal and spatial variations of the index of refraction cause fluctuations of sound phase and amplitude that can be completely understood only by defining the index in terms of the duration, location, range and time of the acoustic experiment. A truncated 'universal' spatial correlation function of the index has been derived from a simplified form of the Kolmogorov-Batchelor spectrum of temperature fluctuations in a homogeneous, isotropic medium. Although this correlation function is shown to be predictable simply from the depth of the experiment, it is of only limited validity with respect to large spatial lags. However, a Gaussian extrapolation of the 'universal' correlation function together with the standard deviation of the index provides simple useful predictions of the sound fluctuations due to temperature microstructure in the upper ocean.
