摘　　要：多波束测深系统越来越被广泛应用于深海调查,并逐渐成为远海综合调查船的标配仪器。利用其开展水深测量作业前对其测深性能进行有效而全面地评估是极为关键的一步。利用2套SeaBeam3012深水多波束测深系统、1套HY1690深水单波束测深系统,在不同条件海域开展一系列系统性试验,并对测深数据分别开展“线与线”、“线与面”及“面与面”的内符合及外符合对比,通过误差统计分析,对待评估多波束测深系统相对精度、绝对精度、波束质量等测深性能展开综合评估,形成一套评估方法。结果证明,上述评估方法是现行技术条件下深水多波束测深系统测深性能综合评估的有效方法。Multi-beam swath bathymeter has recently become a popular tool for deep water surveys and now form an integral part of the deep-sea exploration vessel’s toolkit.Understanding the performance of these systems is a critical step in the deployment of these systems.In this paper, a series of systematic experiments have been carried out in different depth conditions by using one HY1690 deep-water single-beam system and two Seabeam3012 deep-water multi-beam swath bathymeters.Through the "line-line","line-surface","surface-surface" relative and absolute precision analysis, the static precision, dynamic precision, relative precision, absolute precision and beam quality of the multi-beam swath bathymeter have been verified.The result shows that this assessment method is an effective method to demonstrate the overall performance of deep-water multi-beam swath bathymeter under current technical conditions.
