摘要： GeoSwath Plus系统利用相干原理能同时得到水深数据和声纳图,与传统侧扫声纳存在一定差异。本文对GeoSwath Plus 125 kHZ系统和Klein 3000系统从工作原理、技术参数、数据采集和后处理平台以及实测数据等方面进行了对比。结果表明:二者接收数据存在差异,导致两者的用途也存在差异;GeoSwath Plus系统相比Klein 3000更加复杂,但适用水深范围较小;GeoSwath Plus采集软件较少,对后处理软件的要求更高,而Klein 3000数据采集和后处理软件都有多种选择;通过实测数据的比较发现,GeoSwath Plus的定位精度更高,但由于发射波束水平开角大于Klein 3000,加之采用悬挂式安装,导致得到的声纳图像对比度和分辨率比传统侧扫声纳Klein 3000要差一些。

Abstract: Using interferometric principle, GeoSwath Interferometric sonar can get bathymetry data and side scan sonar image. There are some differences between the interferometric systems and traditional side-scan sonar. The GeoSwath Plus System 125 kHz was compared with Klein System 3000 in their theory, technical specification, software and test data. The results show that these two systems are different in types of the acquisition data, which leads to the difference in their purpose. The GeoSwath Plus System is more complex, but its applicable depth is shallower. The kinds of acquisition software which can be used in GeoSwath Plus are less, and its post-processing softwares are required more powerful. But there are more choices for Klein System 3000 in its acquisition and post-processing software. It is found by compared the measured data that the position of GeoSwath Plus image is more accuracy, but the quality and resolution of its sonar image are worse than those from Klein System 3000 because of bigger beam horizontal angle and hanging installation.

Key words: GeoSwath Plus, Klein System 3000, interferometric sonar, side scan sonar, comparison
