A New Solution Method for the Passive Target Motion Analysis Problem using Evolutionary Strategies

Abstract

In this study, the target motion analysis methods, especially used for passive target tracking in submarines, are implemented using evolutionary algorithms. In target motion analysis problem, using a time sequence of transmitted noise directions of a sound source in an acoustic environment; the range, course and speed of the corresponding source are estimated. Size of the search space; ambient noise on the transmission and noise on sensor measurements; decreased observability in different problem scenarios and the need of fast and exact solution, evolutionary strategies, a strong variant of the evolutionary search algorithms, is applied to the problem and efficiency of the results are presented for selected scenarios.
