摘　　要：针对目前国内几款通用的声学地层剖面野外数据采集商业软件,分析探讨了国外软件在数据采集与存储中存在的几个关键缺陷,如GPS滞后、强能量反射同相轴相位与极性改变、深水数据采集存储等严重缺陷。为解决上述缺陷,作者以ChirpⅢ硬件系统为基础,分析国外商业软件缺陷产生的原因,并通过自主研发,提出了解决这些缺陷的方法。经野外实际工作测试,证实了文中所提方法的正确性与可靠性。Based on several foreign commercial software in the field of sub-bottom profile＇s data acquisition which has been widely used in our country,the article analyzes and discusses their several basic defects in data acquisition and storage,such as severe GPS＇s lag,the change of high-energy reflection events＇ phase and polar,data acquisition and storage in deep water,etc.In ordered to resolve the defects mentioned above,Oriented ChirpⅢdevice developed by American Benthos Corporation,the author independently developed the Chinese data acquisition software.By this software,the author analyzes the defects within foreign commercial software and put forward the reliable solu-tions.By actual testing and comparing the data playback,developed software is proved to successfully solve the de-fects existed in foreign commercial software.
