2017    Sonmez, Hasan Huseyin; Hocaoglu, Ali Koksal; Genc, Hakki Murat

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.
