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 ...
A computer technique for near-field analysis of ultrasonic transducer.
(Monterey, California. Naval Postgraduate School, 1973)
A computer technique for obtaining near-field crosssection views of an ultrasonic field is presented. The technique is applied to ultrasonic transducer radiation patterns with sample contour drawings of several ...
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 ...
