Source localization in shallow water in the presence of sensor location uncertainty

The problem of source localization in shallow water in the presence of sens or location uncertainty is considered. The Cramer-Rao Bound is used to carr y out a feasibility study for the joint source and sensor location problem when the multipath propagation channel is modeled as a known, deterministic waveguide. Unlike the free-space propagation channel, the boundedness of t he shallow-water waveguide along its vertical axis provides the key to join t determination of the source and sensor Location parameters. It is seen th at, when a set of intuitive identifiability conditions are satisfied, numer ical examples indicate that, for the scenarios considered, the resulting lo ss in accuracy with which the source location can be estimated due to senso r location uncertainty may be tolerable.
