由澳大利亚国防研究中心研制的“卡里瓦拉”线阵拖曳式声呐已处于研制的最新阶段。1990年12月,澳大利亚海军对该声呐的样机成功地进行了海试。 该线阵拖曳式声。内的湿端设有约1000m长的拖缆.水听器基阵的外径约30mm,为常规线阵的1/3,具有轻便、柔软灵活和易卷绕的特点。该声呐将装在澳大利亚海军正在建造的471型常规潜艇和8艘MEKO 200 ANZAC型护卫舰上。 目前,通用动力公司马可尼水下系统分公司已与澳大利亚国防部签订了使用该声呐技术的合同。
The “Kariwala” linear towed sonar, developed by the Australian Defense Research Center, is in the latest phase of development. In December 1990, the Australian Navy successfully conducted a sea trial on the prototype sonar. The line array towed sound. The wet end of the hydrophone is equipped with a towline of about 1000m in length.The hydrophone array has an outer diameter of about 30mm, which is 1/3 of that of a conventional linear array, which is light, soft, flexible and easy to wind. The sonar will be installed on the 471 conventional submarine under construction by the Australian Navy and eight MEKO 200 ANZAC frigates. At present, General Dynamics Marconi Subsidiary Systems Division has signed a contract with the Australian Department of Defense to use the sonar technology.
