On statistical theory of radar measurements
(Aalto University School of Science, 2012)
Statistical treatment of radar measurements is important as most radar measurements are corrupted by random receiver noise. In addition to this, many radar targets themselves have to be modeled as random processes. It is ...
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 ...
Evaluation of effective eddy diffusive coefficients using radar observations of turbulence in the stratosphere
(American Geophysical Union, 1984-03)
Radar observations show that thin persistent layers of turbulence occur sporadically in the troposphere and stratosphere. Two probabilistic approaches are used to show that the vertical eddy diffusivity due to such layers ...
The Jicamarca phased-array radar
(Institute of Electrical and Electronics Engineers, 2013-10)
Phased array and spaced antenna radar techniques developed and employed at the Jicamarca Radio Observatory for ionospheric research are reviewed. The ionospheric scatterers studied by Jicamarca are not spatially homogeneous ...
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 ...
USO DE IMAGENS DE RADAR NA ESPACIALIZAÇÃO DA TEMPERATURA DO AR
(Universidad de Tarapacá. Facultad de Ciencias Agronómicas, 2010)
Sky-wave over-the-horizon radar simulation tool
(Institution of Engineering and Technology, 2020-11-30)
This work deals with the entire process of target detection and ranging by a sky-wave over-the-horizon radar (OTHR) computational model simulation. The different processing stages of the transmitted signal along its ...
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 ...
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, ...
