潜射反潜自导鱼雷平行航向齐射遮盖目标散布研究

在获取的目标运动要素不完整或目标运动要素误差较大的情况下，潜艇发射反潜自导鱼雷攻击敌潜艇存在较大目标散布。为了提高命中概率，潜艇应组织反潜自导鱼雷齐射。在研究了潜射反潜自导鱼雷平行航向齐射组织方法的基础上，建立了反潜自导鱼雷平行航向齐射遮盖目标散布的数学模型，对不同战术态势下、不同雷数齐射遮盖目标散布的情况进行了计算。研究表明：在设定的战术条件下，中等射距以内2发雷齐射可以遮盖目标散布；大射距大目标运动要素误差情况下4发雷以上齐射可以遮盖目标散布。由于设定的战术条件是任意的，因而研究结论对于潜射反潜自导鱼雷平行航向齐射具有普遍意义。

Study on Salvo of Submarine Launched Anti-submarine Homing Torpedoes for Obscuring Target Scatterance

There is a large target scatterance when a submarine launches anti-submarine acoustic homing torpedoes with incomplete target motion essential or target motion essential which has a big error to attack a hostile submarine. In order to increase the target hit probability, the submarine should execute salvo parallel to the course of the torpedo for attacking the undewater target. Based on the above mentioned salvo method, the mathematic model of obsuring the target scatterance was established and the valid search width-to-the target scatterance projection width ratio was calculated at different tactical situations and the salvo torpedo sums. The calculating results indicate that the salvo with two torpedoes can obscure the target scatterance at middle fire distance, and it will at least need four torpedoes in order to obscure the large target scatterance caused by large fire distance and big error of target motion essential. As the tactical presupposition is arbitrary, the conclusions possess universal significance for obscuring target scatterance of the torpedo salvo.
