Incoherent scattering of radar waves in the auroral ionosphere

Journal of Geophysical Research: Space Physics, 1981
We have systematically studied the effects that non‐Maxwellian ion velocity distributions produce on the ionic part of the spectrum of radar waves incoherently scattered from the disturbed high‐latitude ionosphere in the upper E and lower F regions.

Incoherent Scatter Radar Results

1975
Incoherent scattering is the Thomson scattering of electromagnetic waves of very high frequency (e.g., several hundred MHz) by the free electrons in the ionosphere. In any scattering experiment, the received signal is proportional to a spatial Fourier component of the scatterers density (here the electron density); the relevant wave vector k is mainly ...

AMISR the advanced modular incoherent scatter radar

2013 IEEE International Symposium on Phased Array Systems and Technology, 2013
AMISR is a modular, mobile, UHF radar facility used by scientists and students from around the world to conduct studies of the upper atmosphere and to observe space weather events. SRI International, under a grant from the National Science Foundation, is leading the collaborative effort in the development and operation of AMISR.

A multipulse correlator design for incoherent scatter radar

Radio Science, 1974
A multipulse correlator system for the Chatanika, Alaska, incoherent scatter radar is described. The system utilizes a hardware correlator unit that can deliver as many as 40 8‐bit by 8‐bit lagged products every 20 μsec. The particular lags at which products are computed are patch‐wire programmable, and the range gates at which data are taken are set ...

Modulation patterns for the EISCAT incoherent scatter radar

Journal of Atmospheric and Terrestrial Physics, 1984
Abstract Relatively complicated modulation patterns are needed in order to obtain the necessary spatial and lag domain resolution in studies of the lower part of the ionosphere. Some practical multichannel patterns are presented and their properties are discussed.

Incoherent Scatter Radar (ISR) Systems

1991
An outline of the fundamentals of incoherent scatter theory and its historical development, a description of the milestones of the early development of the technique, and an example of how some ionospheric parameters are measured are given in Section 2.3.2 of this book.

Bayesian filtering for incoherent scatter radar analysis

2020
<p>Electron precipitation and ion frictional heating events cause rapid variations in electron temperature, ion temperature and F1 region ion composition of the high-latitude ionosphere. Four plasma parameters: electron density, electron temperature, ion temperature, and plasma bulk velocity, are typically fitted to incoherent ...

Peculiarities of database for Kharkiv incoherent scatter radar

2017 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo), 2017
The paper presents the structure and peculiarities of the developed database used for Kharkiv incoherent scatter radar data storing. The heterogeneity of the raw data, the existence of specific periods of data acquisition, the use of the IS radar data processing program to estimate size and quality of the data, the use of the external server to store ...

Incoherent-Scatter Radar Observations of the Cusp

1985
With the establishment of the incoherent-scatter radar at Sondre Stromfjord, Greenland, ground-based observations of the dayside auroral oval are now being made. The initial experiments conducted were designed to identify the ionospheric manifestation of the polar cusp in terms of plasma convection and structure in plasma density and temperature.
