Incoherent scattering of electromagnetic waves by a plasma
(Harvard University, 1967)
This thesis is concerned with the theory of incoherent scattering by a plasma, i. e., with the statistical description of the electromagnetic waves scattered by the termal electron density fluctuations in a plasma which ...
Incoherent Scatter Spectral Theories—Part I: A General Framework and Results for Small Magnetic Aspect Angles
(Institute of Electrical and Electronics Engineers, 2010-10-07)
A general framework for the incoherent scatter radar spectral theories is presented in terms of the generalized Nyquist theorem, Kramers-Kronig relations, and the characteristic functions of random charge-carrier displacements ...
Ionospheric electron density and Te/Ti estimation using incoherent scatter power data collected at ALTAIR
(University of Illinois at Urbana-Champaign, 2006)
The main concern of this thesis is the estimation of ionospheric parameters from incoherent scatter (IS) power data collected with the ALTAIR radar. The estimation is performed using a radar calibration and inversion ...
Incoherent scatter radar - spectral signal model and ionospheric applications
(IntechOpen, 2012-04-05)
The chapter is organized as follows: The working principles of ISR’s and the general theory of incoherent scatter spectrum are described in Sections 2 and 3. ISR spectral features in unmagnetized and magnetized plasmas are ...
Incoherent and coherent scatter radar studies of the equatorial F region
(Cornell University, 2008)
Radio waves are weakly scattered by thermal fluctuations in the quasiequilibrium ionospheric plasma. Coherent scatter echoes, meanwhile, are caused by non-thermal electron density fluctuations generated by plasma instabilities ...
Inclination of the geomagnetic field measured by an incoherent scatter technique
(American Geophysical Union, 1971-01-01)
A technique to measure the direction of the geomagnetic field by using incoherent scatter techniques is described. The technique has been used to measure the inclination of the magnetic field at the Jicamarca Radar Observatory ...
Methods for the measurement of vertical ionospheric motions near the magnetic equator by incoherent scattering
(American Geophysical Union, 1969-03-01)
Methods are discussed for the measurement of motions of the ionosphere by means of Doppler shifts of incoherent scatter frequency spectra. It is found that velocities can be measured with an accuracy of better than a few ...
A new approach to computing the incoherent neutron scattering function
(Elsevier, 2021-03)
A new method for calculating the incoherent neutron scattering function for solids is introduced, based on the traditional phonon expansion, where the terms are calculated using the saddle point approximation for each term. ...
High‐altitude incoherent‐scatter measurements at Jicamarca
(American Geophysical Union, 2017-01-31)
In an attempt to reproduce experimental results obtained in the early days of operations, electron density profiles have been measured at the Jicamarca Radio Observatory at altitudes reaching L=2. The methodology involves ...
Mesospheric studies using the Jicamarca incoherent-scatter radar
(Elsevier, 1974-07)
Results from a VHF backscattering experiment using the Jicamarca incoherent-scatter radar are described for a mesospheric height. The echo power during the day varies intermittently and sporadically over a range of almost ...
