Sea surface multitarget track initiation for airborne radar

Aiming at solving the problem of closely spaced targets and glint noise of measurement in the tracking process of sea surface multitarget, this paper proposes a new track initiation algorithm. Compared with the traditional algorithms, the proposed algorithm combines the modified Hough transform with ellipse validation gate to form a new structure, and the maximum likelihood rule is adopted to cut the redundant tracks. Simulation results verify the validity of the novel algorithm.
