| Summary: | Background. The object of the study is the ground location of the MRL antenna
device for the purpose of early, with the maximum possible range, detection of approaching
dangerous weather formation and the formation of a warning signal notifying the relevant
services. This goal is achieved by using a conventional circular-view pulse radar, which
provides, under certain conditions, the maximum value of the line-of-sight range. Materials
and methods. The nature of the dependence of the range of direct radio visibility of the detection
of meteor formation on the level of elevation of the MRL antenna above the Earth’s
surface is shown. The necessary conditions are described to ensure that the maximum possible
value of the line-of-sight range of the detection of the MRL of dangerous meteor formation
is obtained. Results. Mandatory requirements are formulated, compliance with
which is mandatory when choosing the location of the MRL antenna. An approximate calculation
of the value of the range of direct radio visibility is made, for two cases of the
standard location of the MRL transceiver antenna. Conclusions. t is shown that even a
slight rise of the MRL antenna above the earth's surface causes a significant increase in the
value of the range of direct radio visibility. The inadmissibility of angular “shading” of one
or another sector of the azimuth survey is justified, as well as compliance with the actual
location of the MRL antenna from the place of residence of the civilian population, no closer
than the value of the “Rayleigh distance".
