当潜水员在海上营救发生事故的人时，由于海上漂浮的部分障碍物，他们处于危险之中。如果他们能确认自己的立场，他们的活动将变得安全得多。在本研究中，假设我们明确了在事故中救援的潜水员的位置，并支持他们的工作，我们研究了利用低于中波的低频电磁波进行水下定位的技术。在以前的一些研究中，10 kHz的超长波理论上衰减为每米3.5分贝[1]。此外，对该海域垂直剖面的位置估计进行了仿真研究。在这份报告中，我们指出了使用接收信号强度：RSS来表示发射信号和接收信号之间的相位差的优越性。给出了发射天线在2~8m水深范围内的位置估计结果。
When divers rescue people who have accidents at sea, they are in danger because of parts of obstacles floating in the sea. If they can confirm their own positions, their activities will become much safer. In this study, assuming we specify the positions of the divers rescuing in the accidents and support their works, we investigate undersea positioning technology using the electromagnetic waves with low frequencies less than midrange waves. In some preceding studies, an ultra-long wave of 10 kHz theoretically attenuates 3.5 dB per meter [1]. In addition, the simulation of the position estimation in the vertical section of the sea has already reported. In this report, we indicated the superiority of using Receiving Signal Strength: RSS to the phase difference between a transmitted signal and the received one. We also showed the result of the position estimation of the transmitting antenna at depth from 2 m to 8 m.
