Acquiring probability computing model of anti-ship missile based on present position shooting mode

When anti-ship missile adopts present point shooting mode, the computation of the firing data only needs to shoot at target present position without considering target movement and measuring target states during the programmed flight period. Thus the factors that influence the acquiring probability increases and the traditional methods can not reflect the influence of the error on the acquiring probability completely. In this paper, the main error are integrated as target indication precision error and lateral deviation. Different from the traditional methods, target maneuvering limit and target indication accuracy error are both considered as circular distribution. By using analytic method, the computing models of the acquiring probability for anti-ship missile on conditions of different error are built. Finally, the acquiring probability of anti-ship missile with high velocity of sound has been simulated. The results show that two kinds of error both have obvious influence on the acquiring probability. According to the standard that acquiring probability should not be less than 0.99 from the tactics and the demand of the azimuth searching range and target indication accuracy error and lateral deviation of anti-ship missile has been obtained which can be referred by the parameter design of anti-ship missile.
