The Poker Flat, Alaska, MST radar as a meteor radar
Radio Science, 1983Meteor echoes received on the mesosphere‐stratosphere‐troposphere radar at Poker Flat, Alaska, have been tested for their usefulness in studying the large‐scale dynamics of the upper mesosphere and lower ionosphere. A selection scheme has been developed to extract meteor echoes from the normally observed turbulence scatter echoes in a composite data ...

Meteor radar observations at Kyoto University
Journal of Atmospheric and Terrestrial Physics, 1979Abstract A brief description of a coherent-pulse Doppler radar system recently installed at Kyoto and some initial results obtained with it are presented. The solar semidiurnal tide generally dominates the wind oscillations at these heights, while a diurnal tide of comparable magnitude reveals itself in a less regular manner.

Meteor wind observations with the MU radar
Radio Science, 1991We conducted meteor wind observations with the middle and upper atmosphere (MU) radar at Shigaraki, Japan (35°N, 136°E), utilizing an interferometer to determine the arrival angle of a meteor echo. We found that meteor echoes are widely distributed in zenith angles as large as 50° and that the narrow main lobe of a transmitting antenna cannot ...

The new meteor radar at Penn State
2011 XXXth URSI General Assembly and Scientific Symposium, 2011In order to provide new and improved meteor radar sensing capabilities, Penn State has been developing advanced instruments and technologies for future meteor radars, with primary objectives of making such instruments more capable and cost effective to study basic properties of the global meteor flux, such as average mass, velocity, and chemical ...

Optical radar results and meteoric fragmentation
Journal of Geophysical Research, 1964Recent optical radar experiments utilizing a ruby laser as the source of radiation have indicated the existence of a scattering layer in the upper atmosphere at an altitude between 110 and 140 km. The echoes have been tentatively interpreted in accordance with a model of meteoric fragmentation and have been related to other experimental results.
