Experimental investigations of the possible use of TV broadcast signals for determining the drift velocity of meteor trails

Peculiarities of using the TV broadcast signals for radar Doppler measurements of the drift velocity of meteor trails have been considered. A functional block diagram of the measuring apparatus for estimating the Doppler variations of the carrier frequency of TV broadcast signals reflected from drifting meteor trails was proposed. The developed apparatus made it possible for the first time to obtain the experimental proof of the possible use of TV broadcast signals for Doppler radiolocation of meteor trails and investigation of wind-induced motions at heights of the mesopause—lower thermosphere (80–105 km). It was shown that the variations of hourly average values of carrier frequencies of TV broadcast signals reflected from the meteor trails featured the intrinsic relationships typical for Doppler radar observations over the meteor trails drifting under the impact of wind-induced motions at heights 80–105 km
