Features of using the meteorological radar for the assessment of hazardous weather formations

Abstract

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".
