On the characterization of radar receivers for meteor-head echoes studies
(American Geophysical Union, 2013-01)
We report the role that the ambiguity function (AF) plays on the determination of signal to noise ratio (SNR) collected from meteor head echoes. Theoretical analysis shows that any measured meteor SNR exhibits temporal ...
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 ...
Modeling the global micrometeor input function in the upper atmosphere observed by high power and large aperture radars
(American Geophysical Union, 2006-07-26)
We report initial results of an effort to model the diurnal and seasonal variability of the meteor rate detected by high power and large aperture (HPLA) radars. The model uses Monte Carlo simulation techniques and at present ...
First definitive observations of meteor shower particles using a high-power-large-aperture radar
(Elsevier, 2008-03)
We present the first clear observations of meteor shower activity from meteor-head echoes detected by a high-power large-aperture radar (HPLAR). Such observations have been performed at the Jicamarca VHF radar using its ...
Sporadic meteor sources as observed by the Jicamarca high-power large-aperture VHF radar
(Elsevier, 2007-05)
We present, for the first time, the main sources of sporadic meteors as inferred from meteor-head echoes obtained by a high-power large-aperture radar (HPLAR). Such results have been obtained at the Jicamarca HPLAR (11.95° ...
Nonspecular meteor trail altitude distributions and durations observed by a 50 MHz high‐power radar
(American Geophysical Union, 2010-12-30)
High-power large-aperture (HPLA) radars frequently observe nonspecular meteor trail echoes that result from plasma turbulence driven by the intense pressure gradients on the trail edges. This paper analyzes the altitude ...
The case for combining a large low-band very high frequency transmitter with multiple receiving arrays for geospace research: a geospace radar
(American Geophysical Union, 2019-07-09)
We argue that combining a high-power, large-aperture radar transmitter with several large-aperture receiving arrays to make a geospace radar—a radar capable of probing near-Earth space from the upper troposphere through ...
A study on meteor head echo using a probabilistic detection model at Jicamarca
(American Geophysical Union, 2020-01)
A coded long pulse is applied to the Jicamarca 50 MHz high power large aperture radar to study meteor head echoes. We develop a probabilistic detection model, which finds 25% more meteors than the commonly used signal‐to‐noise ...
Observations of meteor-head echoes using the Jicamarca 50 MHz radar in interferometer mode
(European Geosciences Union (EGU), 2004-03)
We present results of recent observations of meteor-head echoes obtained with the high-power largeaperture Jicamarca 50 MHz radar (11.95◦ S, 76.87◦ W) in an interferometric mode. The large power-aperture of the system ...
Southern Argentina Agile Meteor Radar: System design and initial measurements of large-scale winds and tides
(American Geophysical Union, 2010-09)
The Southern Argentina Agile Meteor Radar (SAAMER) was installed at Rio Grande on Tierra del Fuego (53.8°S, 67.8°W) in May 2008 and has been operational for ∼24 months. This paper describes the motivations for the radar ...
