摘要
针对鱼雷的远程自导问题,研究了恶劣水文条件下浅海波导中鱼雷舷侧阵声纳对主动声纳信号的探测能力和测向精度,计算结果表明:在潜艇反舰作战中,通过利用水面舰艇发射的主动声纳信号,可实现潜射鱼雷对目标的远程被动探测,其被动测向精度一般可满足自导精度要求。
The capability of long-range homing forms a key problem in torpedo engineering.In this paper,the detection range and bearing accuracy of active signals by using torpedo flank array sonar under atrocious propagation conditions in shallow water have been investigated for the long-range homing performance of torpedo.The numerical results show that the surface ship can be easily detected by torpedo flank array sonar at long-range distance by interception of the transmitted active pulse signals,and the bearing accuracy can also meet the need for torpedo self-guidance.
