Abstract
The results of the development of a scientific and methodological apparatus that provide an assessment of the detection range of small-sized unmanned aerial vehicles are presented. The general problems of radar detection of small objects are considered. A mathematical formulation of the research problem is carried out from the stand-point of detecting radar signals in noise based on a probabilistic approach. Substantiated are the parameters of radar stations, which are of the most significant importance for increasing the reliability of detecting objects with a small effective scattering surface. The functional dependences of the detection range of small unmanned aerial vehicles on the value of the signal-to-noise ratio in the channel and the sensitivity of the receiving devices are given. The dependence of the detection range on the wavelength of radiation from radar stations has been studied. A quantitative assessment of the probabilities of correct detection of small targets and false alarms is presented for various values of the decision threshold. Nomograms have been developed to assess the capabilities of detectors of unmanned aerial vehicles of the Phantom 3 type. The requirements for the structure of radar signals used to detect small targets are substantiated.
