Abstract
The high-frequency behavior of generalizd ray arrivals is discussed wi th a view towards material characterization by means of measurements o f the dispersion of ultrasonic pulses. The effect of beam spreading is treated exactly. Signal processing algorithms are developed. They are demonstrated with a synthetic signal obtained in an elastic material.
