摘要
对多波束UNB数据文件格式进行了解析,阐述了UNB文件格式的内部记录结构,即系统参数记录、声速剖面记录、导航记录和测深记录等。设计了能读取UNB文件所包含的船参数、声速剖面、导航信息和多波束各波束信息的原始多波束数据格式读取模,经与CTD实测声速剖面得到的数据进行对比可知,读取的结果准确、可靠。
The UNB designed by the New Brunswick University is a universal data format of multi-beam sounding. In this paper, its data structures are analyzed in detail, such as the record of sonar parameters, the record of sound velocity profile, the record of navigation and the record of sounding etc. In the end, a program has been designed and developed successfully to read all the information contained in UNB files. The further work will lay a foundation for the elaborate post-processing of multi-beam sounding, the integrated mapping of topography and the deep application and research based on multi-beam data.
