拖曳线列阵声纳(以下简称拖线阵)采用压力传感器作为获取拖线阵工作深度信息的手段,传统方式是把压力传感器封装在护套内,探头与拖线阵内部填充介质接触,需要扣除内部介质初始压力来获得真实工作深度,由于拖线阵内部填充介质的压力是一个变化量,其大小及变化趋势与多种因素有关,在实际使用中需要经常性的对其进行校准,非常不便。本文分析了造成这种现象的原因,并提出了一种新的应用方式,经过静态压力试验和动态拖曳试验,证明新的应用方式测量准确且免除了经常性校准的烦琐步骤,可以应用到拖线阵中。
Towed array sonar (hereinafter referred to as drag line array) uses pressure sensors as a means of obtaining information about the working depth of the towline array. The traditional method is to encapsulate the pressure sensor in the sheath and the probe needs to be filled with media inside the towing array. Deducting the initial pressure of the internal media to obtain the true working depth, as the pressure within the drag line matrix filling medium is a change in the size and trend of change with a variety of factors related to the need to regularly calibrate in practice, very inconvenient. This paper analyzes the causes of this phenomenon and proposes a new way of application. After static pressure test and dynamic drag test, the new application method is proved to be accurate and eliminates the cumbersome steps of recalibration, which can be applied to the drag Line array.
