Radar/ MST and ST radars and wind profilers
(Academic Press, 2002-12)
To qualify as an MST radar, the system has to be capable of obtaining echoes from the mesosphere. This requirement limits the frequency range of these radars to the lower frequencies of the VHF band, i.e., between 30 and ...
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 ...
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 ...
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 ...
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 ...
On statistical theory of radar measurements
(Aalto University School of Science, 2012)
Statistical treatment of radar measurements is important as most radar measurements are corrupted by random receiver noise. In addition to this, many radar targets themselves have to be modeled as random processes. It is ...
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 ...
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 ...
Detection of stimulated brillouin scattering by the Jicamarca Radar
(American Geophysical Union, 1978-05-01)
Observations of weak stimulated Brillouin scattering with the 50-MHz incoherent scatter radar at Jicamarca are described. The nonlinear interaction of the upgoing radar wave with the downcoming waves incoherently backscattered ...
