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 ...
Transformations of superpositions by means of incoherent operations
(Nature Research, 2020-05)
In this paper we study how the coherence of a superposition of pure states is related with the coherence of its components. We consider two pure initial states and two pure final coherent states, such that the former ones ...
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 ...
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 ...
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 ...
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) ...
Particle dynamics description of ‘‘BGK collisions’’ as a Poisson process
(American Geophysical Union, 2009-07-02)
The Gordeyev integral for plasma particles colliding with neutrals is obtained using a particle dynamics formalism in which the collisions are modeled as a discrete Poisson process. The result leads to an electron density ...
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 ...
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 ...
