远程鱼雷目标主动声纳探测性能分析

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。

Analysis of Detecting Performance of Active Sonar in Long-range Torpedo

According to the shallow-water combat applications of submarine-launched torpedo,three typical hydrological conditions were used to calculate the detecting range and direction-finding error of torpedo 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.
