- In this paper, the path losses between the Jeungdo and Heuksando transceivers located in the coastal areas of Korea are studied using the Advanced Refractive Prediction System simulation software based on the actual coastal weather database. Based on the simulated data, we propose a novel duct map that can effectively estimate the abnormal wave propagation characteristics by using the atmospheric refractive index dependent on altitude as well as the location parameters of Rx and Tx. To verify the proposed duct map, two representative atmospheric index samples are obtained from the 2017 weather database of the Heuksando weather forecast station, causing the abnormal path loss characteristics. The simulated path losses for abnormal conditions at the Rx point are 132.3 and 140.1 dB, respectively, and these results demonstrate that the abnormal radio wave propagation can effectively be predicted through the proposed duct map.
