The Statistics of Finite Bandwidth Modulated Acoustic Signals Propagated to Long Ranges in the Ocean, Including Multiple Source Effects.

Abstract

The statistics of acoustic signals propagated to long ranges in the ocean are investigated in detail in this thesis. The phase random model of multipath propagation is extended to include finite bandwidth and/or modulated sources as well as multiple source configurations. The theoretical analyses include the derivation of many new probability density functions for these new cases as well as for the single narrowband source. The analysis of multiple sources, applicable to noise problems, includes important approximations to densities which are intractable analytically, and would involve significant computer time to solve exactly. In addition to studies of the amplitude densities, significant progress has been made in solving for the amplitude rate densities and the joint densities of amplitude and amplitude rate.
