Abstract: It is known that the enchanting phenomenon of shooting stars in the dark sky is associated with the formation of ionized trails that appears after the invading from space meteoroids. In the visible range, we fix the light with the eye (or an optical device) and astronomers need a dark sky to study the meteor phenomenon in the visible range. Radio technologies make it possible to study meteors day and night, even when the sky is covered with clouds or when the meteors are very weak (or artificial illumination of the sky is significant). In this case, as a rule, not the radio emission of the meteor itself is recorded (the meteor's own radio emission is very weak), but the reflected radiation of an external source from the trail. Meteor radio technologies include semi-active and active radiolocation. The report will pay attention to the problem of meteor radiolocation from the point of view of pollution of certain wave ranges. At the same time, meteor radiolocation is an important modern toolkit. The existing contradiction will be discussed
