摘要
为提高海洋拖曳作业中拖体的定位精度,分析了海洋动态环境对拖体定位的影响,给出了两个主要海洋动态环境要素即海流和航速对拖体定位的补偿模型,对海洋磁力测量、侧扫声纳探测有重大应用价值。
Generally survey vessel travels slowly in marine towing operation, so unsteadily vessel velocity and sea flow influences is obvious. In order to improve the locating accuracy of towed fish pulled by the survey vessel through a long cable, some models are introduced to compensate or remove the dynamic disturbs. The article＇ s methods are significant for improving data quality in marine magnetic detecting and side scan sonar seabed topographic imagining.
