Shallow water reverberation measurement and prediction
(Monterey, California. Naval Postgraduate School, 1994-06)
Low frequency active sonar performance in shallow water is often limited by reverberation. Reverberation modeling in shallow water has been difficult due to the complexity of the multipath acoustic propagation problem ...
Signal processing for the 1992 barents sea tomography experiment
(Monterey, California. Naval Postgraduate School, 1993-12)
In August 1992, an acoustic tomography experiment was conducted in the Barents Sea. The objective of this thesis is the development of space-time signal processing algorithms to extract the arrival times of rays and modes ...
Automatic frequency tracking and an application of target trucking using passive doppler techniques.
(Monterey, California. Naval Postgraduate School, 1974)
A software package was developed to provide the inputs for a passive single-sensor acoustic tracker. This required a computation of sound propagation velocity and resolving high- resolution frequency information from ...
An investigation of the principles and techniques of Bragg diffraction laser beam probing of an ultrasonic field.
Probing of the near field of an ultrasonic beam in water with a thin laser beam has verified that a diffracted beam of light, whose amplitude is a function of the angle of incident light, is related to the spatial Fourier ...
Design of an improved acoustic system for determination of the concentration of microbubbles in the ocean
(Monterey, California. Naval Postgraduate School, 1969-12)
An acoustic system was designed to investigate microbubble concentrations and distributions in the ocean. The system consisted of a one-dimensional standing-wave resonator and a reverberation sensor. Concentrations are ...
