摘　　要：相干声纳系统利用相干原理能同时得到水深数据和声图,与传统侧扫声纳存在着一定的差异。以GeoSwath Plus系统和Kelin3000系统作为代表,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对相干声纳和传统的侧扫声纳进行了对比。结果表明二者的原理类似,但接收数据存在差异;GeoSwath Plus相比Kelin3000更加复杂,但适用水深范围较小;GeoSwath Plus采集软件只能使用GS+软件,对后处理软件的要求更高,而Kelin3000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,但得到的声纳图像对比度和分辨率比传统侧扫声纳要差一些,检测到的目标大小可信度较低。Interferometric sonar system can get bathymetry data and side scan sonar sonogram, using interferometric principle. There are some differences between the interferometric systems and traditional side-scan sonar. The GeoSwath Plus system and Kelin3000 system were compared from their theory, technical specification, software and test data. The two systems are similar in terms of theory, but they are different in types of collecting data. The GeoSwath Plus system is more complex. The acquisition software of Geoswath Plus is only GS＋ software. Its post-processing software is more powerful. But the acquisition and post-processing software of Kelin 3000 is optional. Based on the test data, though the position of Geoswath Plus image is more accuracy, the quality and resolution of its sonar image is worse than traditional side-scan sonar. And the reliability of targets is less.
