The network of the meteor observation in
the radio range consisting of 6 stations located in
Mykolaiv (3 stations), Rivne, Lviv and Hlukhiv has been
created. The main goal of the network is to expand
information about meteor phenomena, including the
assessment of the kinematic parameters (velocities,
radiants and orbital elements) of meteoroids and their
relationship with other small bodies of the Solar system
(potentially hazardous asteroids approaching the Earth).
The operation of the meteor observing hardware and
software complex is based on the continuous receving of
signals from FM radio station reflected from ionized
meteor trains that occur in the Earth's atmosphere at
altitudes of 80-100 km. SDR technology is used to receive
radio signals from over-the-horizon FM broadcast stations
reflected by a meteor train, which has allowed to improve
the sensitivity and frequency selectivity of radio signals.
In 2017–2020 the network registered 1093015 meteors.
The observational data are posted on the RMOB website.
Diurnal variation of meteor counts and comparison with
Perseids meteor stream activity are presented in the work.
