摘　　要：深水多波束测深系统主要应用于高精度全覆盖水下地形测量,随着现代水声技术的发展,其可同时获得海底地貌信息(底质分类)、水柱信息(水体中的油气),成为海洋探测必不可少的设备。对深水多波束测深系统原理、功能、发展做简要介绍,对多波束系统测量误差与精度评估方法进行了初步研究,并利用上海海洋大学"淞航"号首航实测数据,开展了EM302深水多波束测深系统的安置偏移量检校和测深精度评估工作。该工作具有较强实用性,为深水多波束的合理高效使用提供有益的参考。The deepwater multi-beam system is mainly applied in the high-precision & full-coverage bathymetric surveying. With the development of modern hydroacoustic technology, as an essential equipment for marine exploration it can simultaneously obtain seabed geomorphology information(classification of sediment) and water column information(oil and gas in water). In this paper, the principle, function and development of deep water multi-beam system are briefly introduced. The measurement error and accuracy evaluation method of multi-beam system are studied. Based on the measured data of the maiden voyage of Shanghai ocean university "song hang" ship, The offset calibration and accuracy verification of EM302 multi-beam system are carried out. The work in this paper has strong practicability and provides useful reference for the rational and efficient use of the deep water multibeam.
