TIME AND FREQUENCY CHARACTERISTICS OF AN ACOUSTIC SIGNAL REFLECTED FROM A ROUGH BOUNDARY

Abstract

This paper contains an analysis for determining the time of arrival and doppler frequency characteristics of a pulse transmitted to a target by reflection from a not-too-rough surface such as the sea bottom, and gives numerical values for a typical sonar application. The analysis may be important in sonar signal processing associated with one-way or round-trip transmission and in the interpretation of data from marine geophysical surveys; it may in addition have application to propagation of electro-mechanical waves by ionospheric refraction.
