| 摘 要： | 超短基线定位系统可以为水下调查设备提供精确的定位信息,是当今海洋探测工作必不可少的装备。超短基线定位系统的定位结果包含了多种来源的误差影响,对超短基线定位数据进行有效的处理是保证水下精确定位的前提。本文通过对超短基线基阵进行校准,并对其定位精度进行精度评估,对海上应用采集到的数据进行处理分析,对原始数据中出现的跳点进行剔除、滤波处理,得到较可靠的水下定位结果。

| Abstract: | Ultra short baseline positioning system can provide accurate positioning information for underwater equipment. The positioning results of the ultra short baseline positioning system contain a variety of factors, the effective processing of the data is the essential prerequisite for position precision. In this study, the acoustic antenna was calibrated, the accuracy of the positioning data was evaluated, the maritime collecting data were analyzed and the gross points of the raw data were filtered and removed. Finally, the reliable results of underwater positioning thereby can be acquired. |
