Cherniak I. The electron density of ionosphere plasma determination by the method of incoherent scatter of radio waves at dual frequency sounding mode

Investigation subject is a process of incoherent scattering of radiowaves by ionosphere. The aim of study is determination of altitude-temporal variations of ionosphere plasma electron density by the method of incoherent scattering (IS) of radiowaves in heights ranges 100-1000 km simultaneously, improving their accuracy determination. Investigation methods are theoretical and experimental methods of investigations of energy, correlation and spectral IS signal characteristics, altitude-temporal variations of ionosphere electron density. Method of electron density determination in an ionosphere is developed and realized. The generalized model of measuring channel is evolved. Using the developed method, the data about electron density variations in the heights interval 100-1000 km with the improved height resolution during Sun eclipses, magnetic storms, disturbances, caused by rockets starts are obtained. Obtained experimental results essentially promote to the knowledge development on ionosphere and nearspace. The area of application is the fundamental investigations of ionosphere and solar-terrestrial interconnections.The area of application is the fundamental investigations of ionosphere and solar-terrestrial interconnections.
