| 摘 要： | 文章介绍了IXSea Gaps超短基线定位系统及其优势,以及卡尔曼滤波的基本原理、特点、初始值选取和测量过程中所产生的野值的判断准则。在此基础上编写了适用于超短基线定位数据的卡尔曼滤波程序。对水下定位试验所采集的数据进行卡尔曼滤波,得到了较平滑且与原始数据相吻合的滤波数据。

| Abstract: | The ultra-short baseline positioning system and its advantages were described in this paper.Then the basic principles of Kalman filter,its characteristics,the distinguishing criterion of unruly-value occurred during selecting and measuring were also introduced in detail.On this basis,a Kalman filter program for Gaps positioning data was provided.The data of this underwater experiment was filtered by the program, and the filtered data which was smooth and in agreement with the original data was obtained. |
