基于四阵元水听器的被动声纳定位接收装置设计

Design of passive sonar positioning and receiving device-- based on four- element hydrophone

在水下科研试验中经常需要找寻测量声源位置方向,大型水下声纳基阵系统定位精度高,位置精确,但是投入使用的人员,成本也相应的要高,搜索范围固定,在不确定搜索声源位置时使用大型声纳来搜索效果不是很理想。针对大型基阵声纳的局限性,设计一种便携式被动声纳接收装置。该装置可以搭载于机动船上,方便远距离搜索,依靠铅酸电池供电可以支持长达10小时以上连续开机工作,而且具有低成本、低功耗、便携性强等优点。

In the research of underwater scientific measurement, we often need to find the direction of measuring the sound source position. The large-scale underwater sonar array system has high positioning precision and precise position, but the input cost is high. Using a large sonar to search for a sound source location is not ideal. Aiming at the limitation of large array sonar, a portable passive sonar receiver is designed. The device can be mounted on a motor boat to facilitate long-distance search, relying on lead-acid battery-powered can support up to 10 hours continuous boot work, but also has low cost, low power, portability and so on.
