Design of an array based on an antipodal balanced Vivaldi antenna
(Scopus, 2012)
Due to the many breakthroughs in the field of based pulse radars and ultra wide bandwidth (UWB) systems, researches of every component of those systems have been performed in recent years. As well as, in order to match the ...
CLAIRE: An UHF wind profiler radar for turbulence and precipitation studies
(Institute of Electrical and Electronics Engineers, 2017-01-16)
Due to diverse and extreme weather conditions, the Peruvian population is vulnerable to high-impact natural disasters. A continuous monitoring of all weather conditions is necessary for accurate weather models, forecast, ...
Interpretation of angle-of-arrival measurements in the lower atmosphere using spaced antenna radar systems
(American Geophysical Union, 1998-05)
On the basis of scattering theory, we present four different contributions to angle-of-arrival (AOA) measurements using spaced antenna (SA) radar systems. We show that the measurement of the scattering parameters is needed ...
Three-antenna poststatistic steering using the MU radar
(American Geophysical Union, 1990-11)
This paper derives useful expressions for the synthesized beam statistics using poststatistic steenng (PSS), when three antennas are used in a spatial interferometer configuration for twodimensional steering. These antennas ...
Capabilities and limitations of the Jicamarca radar as an MST radar
(1983)
The Jicamarca antenna is the largest radar antenna in the world. It is a flat and almost horizontal array of cross-dipoles, covering an area of 300 m by 300 m (9 Ha). It has a center frequency of 50 MHz with a bnndwidth ...
Optimization of a Balanced Antipodal Vivaldi Antenna for Dual Polarization Ground Penetrating Radar
(Universidad Nacional Tecnológica de Lima Sur, 2020)
In this work, a novel Balanced Antipodal Vivaldi Antenna (BAVA) with 3 Elliptical Slots at the Edges (ESE) is proposed for application in a Dual Polarization Ground Penetrating Radar (DP-GPR). The several antenna parameters ...
Design and implementation of a mechanical system for a ground based synthetic aperture radar with automatic antenna pointing: Preliminary results
(Institute of Electrical and Electronics Engineers, 2018-01)
Melting of the snow covering the Andes mountains is a negative result of climate change. It affects the ecosystem that surrounds the snow peaks causing the loss of water resources the human life. Motivated by this situation, ...
Sousy radar at Jicamarca system description
(Instituto Geofísico del Perú, 2003)
The main characteristics that differentiate the SOUSY radar from the Jicamarca radar are: (1) its bandwidth (4 MHz against 700 KHz for the Jicamarca radar) and (2) its steerability. The wider bandwidth allows an altitude ...
A statistical comparison of horizontal winds obtained by a variety of spaced antenna techniques using the Jicamarca VHF radar
(American Geophysical Union, 1998-11)
We have used the Jicamarca radar system to measure horizontal winds by a variety of time domain and frequency domain spaced antenna techniques. Horizontal wind comparisons for two orthogonal components are carried out in ...
Comparative Analysis of Three Types of VHF/UHF Antennas for GPR Array
(Universidad Nacional Tecnológica de Lima Sur, 2020)
This article presents the comparative analysis of antennas for Ground Penetration Radars (GPR) that operate in the VHF/UHF band around 200 MHz. Three types of antennas are optimized to improve bandwidth, obtain a gain ...
