本文主要涉及多波束测深系统,通过不同的系统在性能、设计理论、调查目的、精度和分辨力、调查效率以及软件功能等方面的比较,我们选择EM950和EM3000多波束测深系统应用于大陆架调查和浅水工程调查。描述了这两种系统的结构和性能,并于1998年4月通过海洋验收试验证明了这两种系统的精度,其结果与Kongsberg Simrad公司提供的技术说明一致。经过野外调查,本文例证了两种要素(运动传感器补偿和声速)影响获得数据质量。

This paper is mainly concerned with Multibeam Echo-Sounder Systems.By comparing different systems in the aspects of system performance, design theory, survey purpose, accuracy and resolution, survey efficiency as well as software functions, we chose EM950 & EM3000 to be applied for "Continental Shelf Survey" and "shallow water engineering survey".This paper describes system configuration and features of EM950 & EM3000.Through Sea Acceptance Test in April of 1998 the accuracy of two systems was proven, consistent with the technical specification provided by Kongsberg Simrad.Through field survey, this paper illustrates there are two factors (motion sensor compensation and sound velocity) mainly effect acquired data quality.
