Abstract:

Problems of information processing and optimal surveillance in a false target environment are investigated with ASW applications in view. The information processing procedures, among other things, make use of adaptive estimation techniques in order to identify uncertain system parameters. Procedures are presented for computing real-time estimates of the target location probability distribution in realistic tactical scenarios involving moving targets and false sensor responses. The procedures are applied to a variety of illustrative examples pertaining to the processing of responses obtained from a fixed sensor field in barrier and area surveillance scenarios. The optimal allocation of ASW search resources in a false target environment is investigated in an exploratory analysis of an idealized surveillance situation.
