| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Underwater acoustic localization is used to know underwater positions in remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs). The ultra-short base-line (USBL) method measures a propagation time of sound wave from a transmitter to a receiver, where distance estimation and direction of arrival (DOA) estimation are performed. In the DOA estimation, the conventional time difference of arrival (TDOA) measurement induces a large error for strong sound wave reflections and the countermeasure against multipath interference is requested. In this paper, we introduce a TDOA algorithm that can reduce the multipath errors, and report on the simulation and experimental results in underwater acoustic localization. | |
