Paper Abstract

In this study, we analyze a specific type of propagation of decameter radio waves connected with lateral reflections of radio signals from ionospheric irregularities at the F-region altitudes. This feature is appeared in registration at the distance-frequency characteristics (ionograms) flat tracks with group paths exceeding ones for standard reflections from F2-region altitudes and maximum observed frequencies (MOF) exceeding MOF1F2. Non-great-circle HF radio signals propagation is considered for the Dikson – Norilsk, Amderma – Norilsk, and Salekhard – Norilsk paths using ionograms obtained in January and April 2016. 79 events of NGC-reflections during the studied period were registered. Among them, 45 events were observed in evening and night hours. Other NGC-events were registered in the day time.
