Radar Meteor Counts: Anomalous Increase during 1963

Science, 1964
Radar meteor counts at Ottawa, Canada, show an increase of up to 50 percent in the hourly rates of short-duration echoes during the middle months of 1963. A similar increase has been observed in the Southern Hemisphere.

METEOR RADAR STATISTICS. II

Canadian Journal of Physics, 1964
Mean daily values of meteor flux for three categories of meteor echoes are tabulated for the period 1958 to 1962. The variation of echo rate with echo duration is studied. The difficulty of using this relation to determine the mass distribution of meteoroids in interplanetary space is noted.

Radar observations of meteors

Proceedings of the Physical Society, 1947
An investigation of short-duration radio echoes observed at 4 to 5 metres wavelength in the neighbourhood of the E region of the ionosphere is described. Observations by vertical beam radio equipments showed that the echoes occurred most frequently at a height of about 95 km.
