Abstract:
A modification is developed for both variants of the single-target ship tracking algorithm of NRL Memorandum Report 4579 AD-A104805. The modification is an improvement in the adaptive procedure for estimating the amount of the ships maneuvering from reports of its location, which can be bearing-only reports in one of the two variants. Tracking performance is improved most markedly when the report occurrences are highly irregular. Experimental FORTRAN implementations and numerical examples are given.
