Study of Daily Variation of Coefficient of Paths Extension by Oblique Sounding with the Russian Chirp Network of Ionosphere Monitoring

摘要

The results of an experimental study of the extension coefficient of HF radio paths of various lengths and geographical orientations using an oblique sounding continuous chirp signal are presented. The results obtained, together with characteristics of means of oblique sounding and a corrected ionosphere model, make it possible to increase the accuracy of recording the coordinates of aerial targets detected by the OTHR.
