潜射声自导鱼雷两雷平行航向齐射遮盖目标散布

Submarine Obscuring Target Scatterance by Launching Two Acoustic Homing Torpedoes With Parallel Salvo

建立了潜艇使用声自导鱼雷两雷平行航向齐射攻击目标的数学模型,对两雷平行航向齐射遮盖目标散布的规律进行了研究.研究结果表明,在对潜艇以一定的精度解算出目标运动要素的情况下,在中等射距、允许的目标舷角范围内,声自导鱼雷两雷平行航向齐射可以遮盖目标散布;目标散布随目标舷角的变化有最小值,但两雷齐射声自导搜索带始终能够遮盖目标散布;随射距的增大,潜艇可以选择的射击阵位范围减小,为了扩大射击阵位的选择范围,潜艇应适当控制射距.

A model of submarine attacking target by launching two acoustic homing torpedoes with parallel salvo was given. The law of obscuring target scatterance of two torpedoes by parallel salvo was studied. Under the conditions of having computed motion factors of target given precision, a submarine launching two acoustic homing torpedoes in the range of middling firing distance and permitted target angle by parallel salvo can obscure the target scatterance in horizontal. The area of target scatterance varies with target angle, and it gets its minimum. However, the hunt cingulum formed by the two acoustic homing torpedoes can always shroud the target scatterance. The allowable firing area of parallel salvo minishes with the increase of firing distance. In order to expand the firing area, the submarine should measurably hold the firing distance.
