Scattering Function of Shallow Water Channels

Abstract

The time and frequency spreading of a shallow water acoustic channel can be characterized by its scattering function. In order to exploit some of the time delay regularities in the acoustic channel, the scattering function is calculated using a Pekeris waveguide model. The correlator loss, which is a measure of the amount of signal spreading caused by the channel, is calculated as a function of range and depth for three well known classes of signals used in active sonar.
