The work examines the prospects of not only recovery, but also simultaneous modernization of meteor radars, which are situated in Balakliia Geophysical Complex. They were created in the 70-80s and are now morally and physically obsolete. It seems inevitable that some parameters of meteor radars will change during modernization. The influence of these parameters on the capabilities of meteor radars is considered. The necessity of using mathematical modeling before the meteor radars modernization “in hardware” is substantiated.
