| Abstract(in English) | In this paper, we propose the precise measurement method of the travel time difference for long-range acoustic reciprocral transmission. In this technique, we estimate the phase difference between the received signal and the reference signal on the complex plane. We present the phase distribution of the received signals with the different SN ratio and the standard deviation of travel time using the simulated signals. Then, we estimate the travel time differences of received signals in the reciprocal transmission data collected during the sound transmission experment by Japan Marine Science and Technology Center (JAMSTEC) in 1999 at the Central Equatorial Pacific. We found the complex vector phase information is useful for the estimation of the travel time difference for ocean acoustic tomography. |
