中文摘要：

以潜射鱼雷的浅海作战应用为背景,结合3种典型水文条件,计算了鱼雷舷侧阵声纳对中频主动声纳信号的作用距离和测向误差。计算结果表明,在潜艇反舰作战中,利用水面舰艇发射的主动声纳信号,潜射鱼雷的舷侧阵声纳可实现目标的远程被动探测;而当目标可探测时,鱼雷舷侧阵声纳具有较高的目标测向精度,一般可满足鱼雷远程自导导引对测向精度的要求。

英文摘要：

According to the shallow-water combat applications of submarine-launched torpedo, three typi- cal hydrological conditions were used to calculate the detecting range and direction-finding error of torpe- do flank array sonar by utilizing the mid-frequency active sonar pulse signals. The results show that, in the anti-ship warfare, the flank array sonar of submarine-launched torpedo can detect a surface target at long distance by intercepting the active pulse signals from the surface target, and the flank array sonar can use for homing due to its high direction-finding accuracy when a target is detected.
