Potential Detection Ranges of UAVs Against the Sky Using a Radiometric System

Today, one of the urgent tasks is the protection of various objects from the influence of unmanned aerial vehicles (UAVs), which pose a potential threat in the military, economic and everyday spheres of human activity. The relatively low cost of UAVs and the difficulty of monitoring and controlling them lead to an increase in impunity and the scale of illegal actions involving their use. The obtained ranges of UAV detection against the background of cloudless and cloudy atmosphere, rain will become the basis for forecasting the effectiveness and development of new technical solutions to increase the capabilities of airspace monitoring tools for UAV detection, which are created for the needs of protecting the critical infrastructure of Ukraine.
