The basic studies on time reversal for underwater acoustic technologies have been carried out by authors, and the method of the acoustic communication using time reversal with adaptive equalizer was proposed. This technique will be applied to long horizontal communication in the deep ocean with an autonomous underwater vehicle (AUV). The experiment was executed in the area at the depth of 1,000m in Suruga-bay. The 500Hz projectors were used, and the range between the focus and the time-reversal array (TRA) was 10 km. Unfortunately, the projector of the TRA side had a breakdown, so it was impossible to execute active time-reversal communication. However, experiments of passive time-reversal communication could be achieved. It was verified that the proposed method enables to assure the communication channel with the TRA of 20 elements.
