Abstract

The widespread use of unmanned aerial vehicles (UAVs), particularly in areas close to airports or critical infrastructure, places new demands on their detection by radar. The work focuses on the obtaining data on the radar cross section for models of UAVs of the aircraft type, with different wing placement relative to the fuselage. The work compares the radar visibility of UAVs of the low-plane, medium-plane and high-plane types, when observed by a radar with a signal fre- quency of 2.8 GHz. The calculation of the radar cross section was carried out by the method of computational electromagnetic modeling using Altair Feko software. The corresponding three-dimensional geometric models of UAVs were constructed using the polygonal mesh method. Based on the modeling, the UAV detection range is estimated depending on the observation angle and under different weather conditions. The results of the work fill gaps in existing re- search on this topic and provide insight into the impact of UAV design on radar detection range. It has been determined that adverse weather conditions, such as thick fog, significantly reduce the radar detection range of UAVs.
