THE BOLOGNA-MODRA FORWARD-SCATTER RADAR EXPERIMENT - REFLECTION PROPERTIES OF METEOR TRAINS

Observational results on the reflection properties of meteor trains ob tained by forward-scatter bistatic radar over the baseline Bologna-Mod ra (about 700 km), as well as some characteristics of the Lyrid shower meteors in 1993, are presented here. The observations following the s hower radiant motion show clearly that the orientation of the baseline of the forward-scatter system is the dominating factor affecting the flux of the recorded meteors. Even the long-enduring meteor trains whi ch were proved to be independent in a backscatter system of the specul ar reflection conditions, are observed herewith to be strongly depende nt on the baseline orientation with a maximum rate corresponding to th e radiants having the baseline as azimuth.
