海洋磁力仪拖体入水深度试验与分析

Test and Analysis on Underwater Depth of Magnetometer Towfish

拖体入水深度是水下拖曳作业的主要参数,其取决于拖体自身重量、拖缆长度和船速。通过G882TVG海洋磁力仪阵列的拖曳试验,分析了船速、配重、拖缆长度的相互关系,导出拖体入水深度计算模型,对类似设备的拖曳参数确定具有借鉴意义。

Underwater depth of towfish is the key factor in marine magnetic detection, which relies on three parameters ： ship velocity, cable length and fish-weight. A G882TVG marine magnetometer is applied in test for obtaining fish＇ s underwater depth. The relationship is researched about ship velocity, cable length and fish- weight, and a model for calculating fish＇ s underwater depth is derived based on the test data. The procedure and methods are helpful to find tow parameters of any other tow devices.
