通过仿真研究了用于长水平通信的时间反转(相位共轭)声学技术,提出了一种将时间反转与自适应均衡器相结合的方法,实现了与稀疏时间反转阵列的通信和与移动水下航行器的通信。本文介绍了在骏河湾进行的实际海实验,实验频率为500 Hz,距离为10 km。在试验中,阵列一侧的投影仪出现了故障。因此,只进行了被动逆时通信实验。经证实,在水深1100米处,采用所提出的方法,仅使用10个阵元就可以实现通信。
We have researched time-reversal (phase-conjugate) acoustic technology for long horizontal communication by simulations, and have proposed a method of combining time reversal and the use of an adaptive equalizer to realize communication even with a sparse time-reversal array and the communication with a moving underwater vehicle. An experiment in a real sea was executed in Suruga-bay at a frequency of 500 Hz at a distance of 10 km, and its results are described in this paper. In the trial, the projector oonlyn the array side malfunctioned. Thus only a passive time-reversal communication experiment was performed. It was confirmed that communication could be achieved using only 10 elements of the array by the proposed method at a water depth of 1,100 m.
