Same night observations of spread‐F by the Jicamarca Radio Observatory in Peru and CUPRI in Alcântara, Brazil
(American Geophysical Union, 1998-01)
50‐MHz echoes from equatorial spread‐F were observed on several nights by both the Jicamarca Radio Observatory (JRO) in Peru and the Cornell University Portable Radar Interferometer (CUPRI) in Alcântara, Brazil. Although ...
Aperture synthesis radar imaging for upper atmospheric research
(IntechOpen, 2012-04)
Radars used for upper-atmospheric applications can be engineered to measure the Doppler spectra of their targets adequately for most intents and purposes, the spectral resolution being limited only by the observing time ...
An intelligent system to real time rainfall prediction using radar data
(Int Inst Informatics & Systemics, 2001-01-01)
This work presents a new approach for rainfall measurements making use of weather radar data for real time application to the radar systems operated by institute of Meteorological Research (IPMET) - UNESP - Bauru - SP-Brazil. ...

(2008-10-03)
RESUMEN: En este trabajo, se desarrollaron algoritmos para determinar la distancia, posición y velocidad de blancos por medio de técnicas utilizadas en un sistema de radar. Para ello, primeramente se describe el funcionamiento ...
Radar images of the Moon at 6-meter wavelength
(Elsevier, 2017-11)
We present new range-Doppler images of the Moon using 6-mwavelength. The radar images were obtained using the Jicamarca Radio Observatory 49.92 MHz radar. The observations were performed using circular polarization on ...
Demodulation of complex baseband radar signals for the analysis of multiple narrow spectral lines
(American Geophysical Union, 1997-03)
This paper proposes a technique for processing signals in which the relevant spectral feature consists of one or more narrow lines which have a nonzero Doppler shift with respect to the reference frequency. The proposed ...
Julia radar studies of electric fields in the equatorial electrojet
(American Geophysical Union, 1997-07)
First results from the JULIA radar at Jicamarca are presented. These include coherent scatter observations of the equatorial electrojet and of 150-km echoes. Interferometry is used to measure the zonal drift rate of kilometer ...
