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 this study, multiple point simultaneous measurement methods with multiple sound source signals are studied and evaluated by simulation and experiment. In the sound-wave reflective environment, the impulse response based generalized cross-correlation function method (IR-GCC-PHAT) showed higher positioning accuracy than the matched filter (MF) method.
