- W2000866235 abstract "본 논문에서는 대략 250 km 이상 떨어져 있는 한국과 일본의 대기 채널 환경에 대한 분석을 하였으며, 대기 굴절도 변화량에 따르는 한일간의 채널 환경에 Radio Duct 현상이 발생하고 있으며, 그로 인한 전파 월경으로 채널 간섭이 발생하고 있음을 확인하였다. 일본 NHK에서 측정한 한국채널 수신전계강도 실험결과를 바탕으로 인접국간 전파예측모델 P 1546의 유효한 굴절도 변화량 보정치로 1% 시간율에서 -91.80 [N-units/km], 10% 시간율에서 -43.92 [N-units/km], 50% 시간율에서 -586.19 [N-units/km]의 보정된 굴절도 변화량을 제시하였으며, 제시된 굴절도 변화량은 한일간의 대기 채널 환경을 반영하는 실질적인 전파모델 예측수행에 기여할 것으로 기대된다. Japan and South Korea since 2004 until now for the broadcast channel interference, by measuring the ongoing conflict are expected to prepare for the future, but Korea's preparation are not enough. In this study, it is pointed that cause of the interference through channel environmental analysis, and effective application of propagation prediction model was carried out between neighboring countries. Between Korea and Japan, radio duct occurs on hold due to changes in the refractive gradient, and comfirmed occurrence of broadcasts interference. The results are presented that 1% time variable, -91.80 [N-units/km], 10% time variable, -43.92 [N-units/km], 50% time variable, -586.19 [N-units/km], for effective refractive gradient. Proposed refractive gradient could contribute to actual radio propagation prediction." @default.
