An Experimental System Based on Pseudo-Scale Model of Air-Sea Two-Layer Problem Operated at 100 MHz

Abstract

To study the electromagnetic field distribution in air-sea two-layer problem for a 10 kHz band undersea location estimation, a 100 MHz band transmitter-receiver experimental setup is constructed in our laboratory using the pseudo-scale model and the electromagnetic field distribution is measured. The received power distribution when the transmitting antenna is placed on the liquid surface and the receiving antenna is scanned underwater is a good agreement with FDTD simulation results, confirming that the measurement is possible even in locations with low receiving strength, including lateral waves.
