Impact of uncertain environmental knowledge on the shallow water transfer function

Abstract

Acoustic source localization (target localization) using an array of sensors is a problem of interest for sonar signal processing. Incorporation of the acoustic channel model into target localization array processing has been shown to perform quite well in many situations. The ability to localize in range, depth and bearing is extremely attractive. An issue of concern is the strong dependence of performance on precise knowledge about the environmental parameters. The objective of this memorandum is to characterize the effect of uncertainty about environmental knowledge on channel-mode localization methods for the shallow-water application.
