Direct detection of ionospheric irregularity

Journal of Atmospheric and Terrestrial Physics, 1969
Abstract A device for the direct detection of ionospheric irregularities was flown on board the 1967-38A San Marco Satellite. This device utilizes the impedance fluctuation induced in the impedance of the satellite antenna by the irregularity. Features of the device as well as typical irregularities observed along the satellite orbits are presented.

Theory of movement of irregularities in the ionosphere

Space Science Reviews, 1965
We review and criticize theoretical works on the movement of irregularities in the ionosphere. It is shown that the basic question of the problem has already been answered. We point out unsolved problems relative to growth and decay of irregularities in an application of the present theories.

Topside irregularities in the equatorial ionosphere

Journal of Atmospheric and Terrestrial Physics, 1977
Abstract This paper is a brief review of ionospheric irregularities in the equatorial topside ionosphere. Results from topside sounders, direct measurement satellites, and the Jicamarca incoherent scatter radar are discussed. Scintillation observations and theories of irregularities are not discussed in detail as these are the subject of other review

Reflexions from irregularities in the ionosphere

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1953
Abstract As part of the investigation of travelling disturbances in the ionosphere during four years, a close study has been made of small daytime changes in the virtual height of F-region reflexions with periods of 10 min to 1 h. In some cases, complex reflexions are observed.

Ionospheric irregularities in the E-region

Journal of Atmospheric and Terrestrial Physics, 1972
Abstract Phase path measurements have been used to study E -region irregularities. Power spectral analysis of records taken when only one reflection point was present showed that the most prominent variations in phase path occurred at periods greater than a few minutes, with a spectral peak appearing at a period of about 5 min.

On the Gravity Wave‐Seeded Ionospheric Irregularities in the Martian Ionosphere

Journal of Geophysical Research: Planets
Abstract For the past few decades, it has been demonstrated that gravity waves (GWs) and neutral winds can drive ionospheric irregularities on Earth. Still, as far as we know, the formation of ionospheric irregularities on Mars due to GWs has not been well studied.

High-Latitude Ionospheric Irregularities.

1986
Abstract : This document summarizes studies on the morphology of ionospheric structure at high latitudes. The program encompasses both theoretical and experimental investigations into this rapidly developing field. Because of the vast range of scale sizes (hundreds of kilometers to centimeters) that make up the structure, and the need for time ...
