(meteorobs) [meteorobs] radar radiant sizes

[STEFANO FERRETTI]

Hello!
I'm new in the list.
I'm an astronomy graduating student of the University of Bologna(Italy).
Actually I'm working on my theses (concerning radiant mapping) at the isac 
institute, where a forward-scatter meteor radar facility is in use (even 
though mostly for rating, so far...).
In fact, I'm exspecially interested in radar methods for radiant 
determinations, that is what I'm focusing on.
I'm looking for someone fond of this subject because I've some questions: 
had the sizes of radar radiants ever been tabulated?where can I find these 
data?
I suppouse these sizes to be larger than the visual ones, since radars can 
observe fainter meteors, and therefore more dispersed....but how much?
All the help will be appreciated.
Thanks

Stefano
