| Abstract(in English) | The authors deal with the problem of position estimation in the sea using electromagnetic waves as one of the applications of electromagnetic waves in the sea. The attenuation of electromagnetic waves at high frequencies is large in the sea, so we are investigating the possibility of communication by electromagnetic waves at relatively close distances using frequencies in the kHz band. From the viewpoint of measurement dynamic range, amplitude measurement is advantageous compared to phase measurement, and our attention should be paid to amplitude attenuation in the sea and at sea level. The authors examined the possibility of phase measurement, focusing on the problem of undersea location estimation, as a comparative study. In this paper, we report our experimental verification for the phase measurement using a pseudo-scale model. |
