• Observations of Anomaly in Oversea Long Distance Propagation of TV Broadcasting Waves.

抄録

We observed broadband spectra in VHF band at Tateyama, Japan, to investigate anomaly in long distance propagation of TV broadcasting waves. We found that TV broadcasting waves from Malaysia at 48.25MHz (distance is 5200km) and China at 49.75MHz (distance is 1800km) can sometimes propagate. Seasonal and daily variations of received broadcasting waves were investigated through one-year observations. Malaysia broadcasting waves were frequently received in spring and autumn, but China broadcasting waves were received mainly in summer. We may conclude that radio waves of Malaysia TV are reflected by F2 layer and those of China TV are reflected by sporadic E layer in summer in the ionosphere.
