工作母船漂移对鱼雷被动声自导攻击固定靶试验的影响与修正

Influence of Supporting Vehicle Drift on Passive Acoustic Homing Torpedo Attacking Fixed Target Test and Correction Method

鱼雷被动声自导攻击固定靶试验是考核被动声自导作用距离是否满足研制总要求的重要依据,但被动声自导捕获声靶距离不仅与自导系统性能有关,还与试验态势有着密切的关系。在分析被动声自导鱼雷接收波束配置、攻击固定靶试验航路与工作母船漂移的基础上,建立起工作母船漂移对被动声自导捕获声靶距离的影响模型,进而给出了漂移修正方法。最后结合算例进行分析,验证了该方法的有效性。

The attacking fixed target test of a passive acoustic homing torpedo is important for assessing whether its passive acoustic homing range satisfies the general requirement of design. The passive acoustic homing distance for a torpedo to capture target is related to the performance of the homing system and the test situation. In this paper, the receiving beam configuration of the passive acoustic homing torpedo, the test route of attacking a fixed target and the supporting vehicle drift are analyzed, an influencing model of supporting vehicle drift on capturing target distance of the passive acoustic homing torpedo is established, and a drift correction method is proposed. A practical example verifies the effectiveness of this method.
