We previously studied long horizontal time-reversal (phase-conjugate) communication based on simulations and at-sea experiments. In these previous experiments, time-reversal communication at ranges of 10 to 100 km was achieved. In the implementation of time-reversal communication, it is prerequisite that the reciprocity of the medium is retained. Therefore, it is necessary to investigate the effects of nonreciprocal disturbances, such as movements of source-receiver or current flow. The effect of the movement of source receiver was studied in previous works. In this paper, the effect of current flow is studied on the basis of simulations. The results show that the effects of current flow appear mainly as stationary phase deviation. The method of combining time reversal and adaptive equalization, which we have proposed in our previous works, can compensate the current flow-induced effect and enable communication if the current flow speed is not so high.
