  Abstract

In this paper, channel modeling was performed using a spherical earth reflection model for C-band long-distance ship-to-ground communications. A unique wireless communication environment in which the LOS(Line of Sight) is always present was considered because a high-gain antenna over 30 dBi is mounted on the stabilizer and the positioner on the ship and the ground. The received signal strength was measured when the ship moved the point of 24km to 50km from the ground, and it was confirmed that it was in good agreement with the channel model result predicted by the spherical earth reflection model. Based on the channel model, two kinds of fading overcoming method were proposed using antenna height adjustment and beam steering. By applying the antenna height adjustment method, fading can be basically eliminated. And through the beam steering, the received signal strength was increased by 5 dB in the area where deep fading occurs.
