We present joint optical-radar observations of meteors collected near the peak of the Leonid activity in 2002. We show four examples of joint detections with a large, phased array L-band radar and wit...
Radar observations of meteor trails, and their interpretation using Fresnel holography: a new tool in meteor science
meteor trails Fresnel holography meteor science
2009/2/27
A Fresnel transform technique has been developed at Adelaide to analyse radar meteor echoes detected in the transverse mode. The genesis for this technique was the study of the structure of the scatte...
The radar system described here (CMOR) comprises a basic 5-element receiving system, co-located with a pulsed transmitter, specifically designed to observe meteor echoes and to determine their positio...
Radiant measurement accuracy of micrometeors detected by the Arecibo 430 MHz Dual-Beam Radar
Radiant measurement micrometeors Arecibo 430 MHz Dual-Beam Radar
2009/2/25
Precise knowledge of the angle between the meteor vector velocity and the radar beam axis is one of the largest source of errors in the Arecibo Observatory (AO) micrometeor observations. In this paper...
Isolated lower mesospheric echoes seen by medium frequency radar at 70° N, 19° E
Isolated lower mesospheric echoes medium frequency radar
2009/1/20
We have noted sporadic instances of strong isolated reflections of medium frequency (MF) radar waves from the mesosphere from as low as 50 km altitude and have devised a set of criteria for isolating ...
Evaluation of radar multiple scattering effects in Cloudsat configuration
radar multiple scattering effects Cloudsat configuration
2008/12/5
MonteCarlo simulations have been performed to evaluate the importance of multiple scattering effects in co- and cross-polar radar returns for 94 GHz radars in Cloudsat and airborne configurations. Tho...
A long-term comparison of wind and tide measurements in the upper mesosphere recorded with an imaging Doppler interferometer and SuperDARN radar at Halley, Antarctica
comparison tide measurements pper mesosphere imaging Doppler interferometer SuperDARN radar
2008/10/31
Data from a near co-located imaging Doppler interferometer (IDI) and SuperDARN radar recorded since 1996 have been analysed in a consistent manner to compare the derived mean winds and tides in the up...
