Radar observations of two‐dimensional turbulence in the equatorial electrojet, 2
(American Geophysical Union, 1976-01-01)
Observations with an altitude resolution of about 1 km were made with the large, vertically directed 50‐MHz radar system at the Jicamarca Radar Observatory during the day, when the electrojet was strong. Type 1 (‘two ...
Equatorial F-region plasma density estimation with incoherent scatter radar using a transverse-mode differential-phase method
(University of Illinois at Urbana-Champaign, 2002)
Esta tesis presenta un método de adquisición y análisis de datos novedoso para radar de dispersión incoherente Jicamarca para medir derivas de alta precisión y la densidad ionosférica simultáneamente en las alturas de la ...
Scientific contributions of the Jicamarca Observatory peculiar to its equatorial latitude of operating frequency
(Instituto Panamericano de Geografia e Historia, 1983-01)
We shall limit ourselves here to a brief discussion of the work done at the Jicamarca Observatory connected either with: a) the geometry of the Magnetic Field or, b) with backscatter from enhanced fluctuations (non-thermal) ...
On a correlation between the ionospheric electric field and the time derivative of the magnetic field
(Hindawi, 2012-02-20)
A correlation of the ionospheric electric field and the time derivative of the magnetic field was noticed over thirty years ago and has yet to be explained. Here we report on another set of examples during the superstorm ...
Electron density profiles in the equatorial E region ionosphere derived from a bistatic coherent scatter radar experiment in Perú
(American Geophysical Union, 2005-01-14)
A new bistatic radar system has been developed at the Jicamarca Radio Observatory. The system is a permanent addition to the facility designed to monitor electron density profiles in the equatorial electrojet region using ...
Performance evaluation of the particle swarm optimization algorithm to unambiguously estimate plasma parameters from incoherent scatter radar signals
(Springer, 2020)
Simultaneously estimating plasma parameters of the ionosphere presents a problem for the incoherent scatter radar
(ISR) technique at altitudes between ~ 130 and ~ 300 km. Different mixtures of ion concentrations and ...
Mesospheric wind and aspect sensitivity measurements at Jicamarca using radar interferometry and poststatistics steering techniques
(American Geophysical Union, 1990-08)
Spectral and cross-spectral signatures of lower mesospheric radar returns are investigated and modeled. Aspect sensitivity of radar echoes and the horizontal, vertical, and random components of atmospheric fluid velocity ...
Sudden disappearance of vhf radar echoes from equatorial e-region irregularities
(Council of Scientific and Industrial Research, 1977-01)
The Modified Range Time lntensity Technique for studying the height variation of the (back-scatter power of vhf radar echoes at Jicamarca has been used to show that the growth lime of E-region irregularities is less than ...
Incoherent Scatter Spectral Theories—Part II: Modeling the Spectrum for Modes Propagating Perpendicular to B
(Institute of Electrical and Electronics Engineers, 2011-10-07)
Incoherent scatter (IS) spectral models for collisional and magnetized F-region plasmas are developed based on a general framework described in part I of this paper and on the statistics of simulated particle trajectories. ...
Spectral parameter estimation of CAT radar echoes in the presence of fading clutter
(American Geophysical Union, 1982-07)
The 430 MHz, 2 MW radar at the Arecibo Observatory is currently being used as a stratospheric-troposheric (ST) radar. One of the problems in the automatic analysis of the signals come from the very large amplitude of the ...
