- Abstract
- Radio interference has been occurring in the TRS service on the south seashore in Korea from 1994. After monitoring the radio signal interference, it was found that the main reasons for the radio interference are due to the radio ducting signal from the seaside of Japan. In this paper, an APM (advanced propagation model) to analyze tropospheric radiowave propagation over the sea surface in the presence of range-dependent refractivity is presented. The propagation loss in ducts is calculated using the model and compared with the interference experimental data gathered in 1999 between Korea and Japan. Also we suggest the parameter values, for example transmitting antenna height, receiving antenna height which minimize the interference between nations through simulation results.
