摘　　要：ADCP资料后处理是海流研究过程中的重要环节。为进一步丰富该类型数据的处理思路与处理手段,系统性地介绍了法国海洋开发研究院研发的船载ADCP资料处理软件Cascade7.2,详细阐述了Cascade7.2资料处理的基本流程、思路、主要功能和部分原理,并结合一段实测数据,通过对比国内某同类产品,对该软件开展初步应用。资料处理流程表明,Cascade7.2软件集成了数据处理、成图和参数校正等功能,采用问题数据标记的方式,有效避免数据误删;处理结果表明该软件使用了加权三点滑动平均方式进行滤波,提升了资料处理效率,但在数据平滑性上略差。ADCP data post-processing is an important part of the ocean current research process.In order to further enrich the processing ideas and methods of this type of data, the paper systematically introduces the shipborne ADCP data processing software Cascade7.2 developed by the French Ocean Development Institute, including the basic process, ideas, main functions and some principles.Based on a piece of measured data, comparing with a domestic similar product, the paper carries out preliminary application.The data processing flow shows that the Cascade7.2 software integrates data processing, mapping and parameter correction functions, and uses problem data marking to effectively avoid the incorrect deletion of data;The processing result shows that the Cascade7.2 software uses a weighted three-point moving average method for filtering, which improves the efficiency of data processing, but the smoothness of processed data is slightly worse.
