| Abstract(in English) | Ocean Acoustic Tomography (OAT) is a powerful approach for observation of mesoscale ocean fluctuations. It is required the precise estimation of travel time for the ocean current measurement. In this paper, we investigated the stability of reciprocal acoustic transmission using 500 km and 1000 km data of OAT experiment performed at the Central Equatorial Pacific in 1999. Cross correlation values of reciprocal transmission signals were calculated. In 500 km data, we found the multi-path structure that causes the low cross correlation value at irregular intervals. In 1000 km data, the structure of received signals are simple and the cross correlation values are high. We got the acoustic characteristics of reciprocal transmission signals that are useful fot the estimation of travel time difference. |
