摘要

水下运动目标的定位和跟踪在许多应用中都很重要。本文介绍了2013年5月在台湾高雄附近的四子焕沿海地区进行的水下定位海上试验,其中使用三个固定节点通过基于正交频分复用(OFDM)调制解调器的声学通信来定位一个移动节点。实验结果表明,估计的水下移动节点轨迹与全球定位系统记录的轨迹吻合较好。

A sea test of mobile underwater localization
Localization and tracking of underwater moving objects are of great interest in many applications. This paper presents a recent sea test on underwater localization carried out in the Sizihwan coastal area near Kaohsiung, Taiwan, May 2013, where three stationary nodes are used to localize one mobile node via acoustic communications based on orthogonal frequency-division multiplexing (OFDM) modems. Experimental results show that the estimated trajectory of the underwater mobile node agrees well with the track recorded by global positioning system (GPS).
