| description | The reasons for scatter in plots of log(inverse decay times) vs. height
for radio meteor echoes are examined, and an explanation for the
characteristics is offered.
Effects like temperature variability, pressure variation,
angular detection accuracy, pulse length, phase errors, plasma processes
and variation in meteoroid metallic content are considered. Using computer
simulations the observed scatter is reproduced to good accuracy,
and then these results are utilized to develop a new
procedure that can be used to determine temperatures in the meteor
region. These same studies also permit determination of some
limited information about the nature of the diffusive expansion
process and the variability
in the metallic content of meteors.
The impact of the quality of phase calibration of interferometric
radars on accurate reproduction of atmospheric temperatures
is also examined. |
