Determining the Position and Properties of the Region of Artificial Ionospheric Irregularities Above the Sura Facility Responsible for Generation of Aspect Scattering Signals on a Short Path

Abstract

The data obtained in the experiments on aspect scattering on a short path of Kazan—Vasilsursk—Kazan performed at the Sura facility in 2010 at frequencies of 2–7 MHz are compared with the results of ray-tracing calculations of the sounding and scattered signals. Positions and sizes of the region above Sura responsible for generation of the aspect scattering signals are determined. Characteristic scales of artificial decameter scattering irregularities and their dynamic properties as functions of the generation altitude and the time of the day are found.
