O článku:
The theoretical radar meteors Range Distribution of the overdense echoes
range distributions of meteors belonging to the Quadrantid, Perseid, Leonid,
Geminid, γ Draconid (Giacobinid), ζ Perseid and
β Taurid
streams to study the variability of the shape-density, ablation, and
self-similarity parameters of meteoroids of these streams. We have found
in accordance with results of photographical observations that ablation
parameter σ is higher for members of showers of clearly cometary
origin, and is lower for Geminid and daytime shower meteoroids. Levin's
self-similarity parameter μ was found to be much greater than the
classical value 2/3 for all investigated streams with the exception of
Geminids, for which the value found is almost classical, i.e. 0.66 ±
0.01. The method of getting μ by means of fitting the light curve of
faint TV meteors is also suggested.
