潜艇平行航向齐射两枚鱼雷时相对目标方位开角研究

舰艇对潜艇平行航向齐射两枚鱼雷的方位分辨能力对水声对抗指挥决策具有重要影响。在研究潜射自导鱼雷平行航向齐射组织方法的基础上，建立了潜艇齐射两枚鱼雷相对舰艇目标方位开角的数学模型，对不同对抗态势和战术条件下齐射两枚鱼雷相对舰艇开角大小及其影响因素进行了计算分析。结果表明：齐射两枚鱼雷相对目标方位开角与来袭鱼雷报警距离、鱼雷的齐射时间间隔、优化系数、鱼雷的自导性能等因素有关，在通常的战术条件下齐射两枚鱼雷相对目标的方位开角在3°~7°之间，现有舰艇声纳难以准确分辨出齐射的两枚鱼雷，通常只能按一批鱼雷目标进行报警和对抗。

Study on Orientation Angle of Two Acoustic Homing Torpedoes Relative to Target with Parallel Salvo Launched by Submarine

The orientation resolution capacity of surface to two acoustic homing torpedoes with parallel salvo launched by submarine has important influence on command and decision-making of underwater acoustic warfare.Based on the above mentioned parallel salvo method,the mathematic model of the orientation angle of two torpedoes relative to target was established.The orientation angle of two torpedoes to target and its influence factors were calculated and analyzed at different tactical situations.The results indicate the orientation angle of two torpedoes is influenced by alarm distance of oncoming torpedo,salvo interval,salvo optimization coefficient,and homing performance of torpedo etc,and the orientation angle of two salvo torpedoes relative to target is about 3°~7° under the usual tactical condition.As the existing sonar could not differentiate the two torpedoes with parallel salvo veraciously,surface ship gives alarm and counters the two torpedoes as one torpedo usually.
