Abstract :
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).
