海岸声纳 设置在近岸海域的固定式声纳。是海岸防潜警戒系统的主要水中探测设备。由水听器基阵、海底电缆、岸上电子设备和电源等组成。用于海峡、基地、港口、航道和近海水域对潜警戒，并引导岸基或海上的反潜兵力实施对潜攻击。海岸声纳的工作方式有主动式和被动式两种，通常以被动式为主。当基阵接收到潜艇的噪声或回声信号时，把它转换成电信号，通过海底电缆传送到岸上的电子设备，经处理后供显示和收听，并将目标数据传送给海岸防潜作战指挥系统。海岸声纳被动式探测距离为20～30海里，最大可达70海里。海岸声纳主动式利用布放在深海声道中的基阵，接收由反潜飞机或舰艇投掷的水声信号弹的爆炸声波碰到潜艇反射的回声，探测距离可达100海里。海岸声纳的隐蔽性好,探测距离较远，但其基阵体积庞大，海上安装和维修困难，其性能易受水文气象条件和底质的影响。 随着核动力战略导弹潜艇的出现，需要增大防潜警戒系统的纵深，发展了由海岸声纳、锚系声纳浮标和深海基阵组成的水下区域性对潜监视系统；20世纪80年代，又进一步向全球性的全时对潜监视跟踪系统的方向发展。
