G. Cevolani et al., BASE-LINE EFFECT ON THE FORWARD-SCATTER RADAR REFLECTIONS FROM METEORTRAINS, Nuovo cimento della Societa italiana di fisica. C, Geophysics and space physics, 19(3), 1996, pp. 447-450
The influence of the baseline orientation on the rate of recorded mete
or echoes has been shown from the observations carried out during the
Lyrid meteor shower periods in 1992 and 1993 with receivers rectangula
rly displaced from the transmitting station in Bologna with a baseline
length of about 700 km. It is shown that the maximum echo rate preced
es or occurs later than the shower radiant culminates (at heights of 8
0 degrees), favouring the 45 degrees radiant elevation and similar ang
le between the radiant and the beam axis. The consequences of the meas
ured effect on the meteor flux within the shower and sporadic radiant
distribution is discussed.
