Introduction,nt techniques. During their more than 70-year history, these methods proved to be most contributory to the investigation of the ionospheric structure — the main body of facts has been obtained by just radio sounding methods. Optical methods for ionosphere diagnostics have also been successfully used for many years.

Ionosphere: Structure and Basic Methods for Radio Sounding and Monitoring,dio probing of the ionosphere. In Russia, the first results in this field were obtained by M.V. Shuleykin who inferred from studying the operation of broadcasting stations that a radio wave exists that comes from above to Earth’s surface. He calculated the reflection height as 260 km.

Ray Radio Tomography,e.g., the ionospheric trough) and artificial (spacecraft traces, technological emissions), are of the order of dozens to thousands of kilometers, diffraction effects can be neglected in VLF/UHF probing.

Further Development of Tomographic Methods,phere over a set of quasi-tangential rays. In particular, nowadays, most promising for ionospheric and atmospheric investigations are the systems mounted in low-and middle-orbiting satellites that receive radio signals from navigational systems such as GPS/GLONASS.
