Preliminary AMISR-14 radar observations of F-region incoherent backscatter echoes at the Jicamarca Radio Observatory (JRO)
(2022 CEDAR Workshop, 2022-06)
A 14-panel Advanced Modular Incoherent Scatter Radar (AMISR-14) was installed at the Jicamarca Radio Observatory (IGP- JRO) in 2014. Because of its size, this radar was mainly used to observe coherent echoes such as those ...
Quasi-complementary codes: A new technique for MST radar sounding
(American Geophysical Union, 1984-01)
The binary phase complementary code set has been used in stratospheric radar sounding. The quasi-complementary code technique presented here has nearly complementary properties and offers significant reduction of side lobes ...
F-region electron density and Te / Ti measurements using incoherent scatter power data collected at ALTAIR
(European Geosciences Union (EGU), 2006-07)
The ALTAIR UHF radar was used in an incoherent scatter experiment to observe the low-latitude ionosphere during the Equis 2 rocket campaign. The measurements provided the first high-resolution electron density maps of the ...
A multi-beam incoherent scatter radar technique for the estimation of ionospheric electron density and Te/Ti profiles at Jicamarca
(Elsevier, 2013-12)
A multi-beam incoherent scatter radar technique has been developed at the Jicamarca Radio Observatory in order to maximize the number of ionospheric parameters that can be estimated simultaneously. The technique interleaves ...
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 ...
Incoherent scatter radar plasma density measurements at Jicamarca using a transverse-mode differential-phase method
(American Geophysical Union, 2003)
The 50 MHz Jicamarca incoherent scatter radar can be used to make very high precision F-region plasma drift measurements with less than a m/s uncertainty and 5 min/ 15 km time/height resolutions. In such measurements the ...
Calibration of Jicamarca radar using F-region incoherent scatter for measurements of D-region backscatter RCS
(University of Illinois at Urbana-Champaign, 2007)
El propósito de esta tesis es describir las mediciones del radar calibrado de absoluta retrodispersión a traves de las secciones mesososféricas de los ecos del radar observados en el Radio Observatorio de Jicamarca en Perú. ...
Pulse compression hardware decoding techniques for MST radars
(American Geophysical Union, 1985-11)
The techniques for decoding in hardware received signals transmitted by phase‐coded mesosphere‐stratosphere‐troposphere (MST) radars are reviewed. The designs consist of digital and analog types which resemble filters or ...
Spectral Analysis of Incoherent Scatter Radar Signals in Faraday/Double Pulse Experiments at the Jicamarca Radio Observatory
(IEEE, Institute of Electrical and Electronics Engineers, 2021)
The Jicamarca incoherent scatter radar can be operated in different modes to measure the main physical parameters of the equatorial ionosphere. One of these modes is the Faraday/Double Pulse experiment that was designed ...
East-west ionospheric drifts at the magnetic equator
(Instituto Geofísico del Perú, 1972-01-01)
A technique has been developed to measure the electromagnetic east-west drift velocity of the F region ionosphere by means of the Jicamarca incoherent scatter radar. Results show a fairly consistent behavior from day to ...
