Jicamarca incoherent and coherent scatter radar capabilities for equatorial aeronomy
(European Geosciences Union, 2005)
"The International Symposium on Equatorial Aeronomy is held approximately every three to four years and is typically a major gathering of scientists from around the world interested in the low-latitude atmosphere and ...
Incoherent scatter measurements of aurora-like ion beam distribution and ionospheric holes produced by the space shuttle flying over the radars at Jicamarca, Kwajalein, and Arecibo
(Instituto Geofísico del Perú, 2000)
In October 1997 and July 1999 during the STS-86 and STS-93 flights of the Space Shuttle, the crew performed experiments with controlled ion injections over the incoherent scatter radar (ISR) facilities located at Arecibo, ...
Radar Observations of Equatorial Ionospheric Irregularities
(International Science Congress Association, 2015-10-24)
Long-term data set of radar observations using coherent and incoherent scatter radar sources during 1996-2008 were used to study the trend of low-latitude ionospheric irregularities, also referred to as equatorial spread ...
The early history of the Jicamarca Radio Observatory and the incoherent scatter technique
(Copernicus Publications, 2019-10-02)
The purpose of these historical notes is to present the early history of the Jicamarca Radio Observatory (JRO), a research facility that has been conducting observations and studies of the equatorial ionosphere for more ...
Incoherent backscatter radar measurements at Jicamarca with a beam pointed perpendicular to
(Instituto Geofísico del Perú, 2000)
Doppler spectra of 50 MHz F-region incoherent backscattered signals detected at Jicamarca will be presented. The measurements were conducted with the Jicamarca radar beams pointed perpendicular to the ambient magnetic field ...
Study of Coulomb collisions and magneto-ionic propagation effects on incoherent scatter radar measurements at Jicamarca
(University of Illinois at Urbana-Champaign, 2010)
In this dissertation, Coulomb collisions and magnetoionic propagation effects on the incoherent scatter radar measurements have been studied and analyzed in detail. The present study aims at modeling radar observations of ...
Radar observations of equatorial spread F in a region of electrostatic turbulence
(American Geophysical Union, 1972-10-01)
Radar observations of a welldeveloped layer of strong equatorial spread F are presented. The scattering cross section, correlation lifetime, and vertical electromagnetic drift velocity of the spread-F irregularities were ...
Comparison of Te and Ti from Ogo 6 and from various incoherent scatter radars
(American Geophysical Union, 1973-01-01)
Langmuir probe and retarding potential analyzer (RPA) data on the electron and ion temperatures Te and Ti obtained from Ogo 6 are compared with Te and Ti values obtained from the incoherent scatter network. The satellite ...
Spectral moment estimation in MST radars
(American Geophysical Union, 1985-11)
Processing techniques for the estimation of the power, the frequency shift, and the spectral width of mesosphere-stratosphere-troposphere (MST) radar returns are presented. The differential techniques are compared in terms ...
Fine altitude resolution radar observations of upper-tropospheric and lower-stratospheric winds and waves
(American Meteorological Society, 1982-07-26)
Preliminary results of wind velocity measurements made using the Arecíbo 430 MHz radar are presented. These measurements were made in the altitude range between 10 and 30 km, with a time resolution of 1-2 min, and an ...
