Abstract: In view of that the current admission comparing searching mode is difficult to adapt to the offshore operation of anti-ship missile in multi target selection, the nearest neighbor selector applied to the target search scheme is put forward. By setting the typical searching situation, a target searching model is established; and on the basis of reasonable simplification, the nearest neighbor selector capture probability of display expression is deduced. Typical scenes in numerical simulation show that the scheme based on distance criterion for admission multiple targets for prioritization effectively improves the search performance of the target. A quantitative effect assessment on search area, admission number of objects, target scattering error and other factors is carried out. The defects of using the nearest neighbor multi target selection are pointed out, and the corresponding improvement measures are put forward.

Key words: Anti-ship missile, multi target selection, nearest neighbor, search probability
