Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) detection, in particular to an UAV equipped with a radar. Background Art

[0002] Existing drone detection technologies mostly install radars in fixed locations to detect aerial targets. This requires an elevated platform for the radar equipment in situations with numerous obstacles. Other vehicle-mounted or portable radars, while more maneuverable, still struggle with obstacles. With the advancement of drone technology, drones are finding a wider range of applications, leading to the emergence of drones equipped with radars. Existing drones and radars are connected via adapter plates, with the drone and radar devices often being installed separately. For radar-based drone integration requiring azimuth and pitch rotation, poor integration of these mechanisms can significantly increase the drone's load and energy consumption. Furthermore, if the radar's headwind remains constant, a larger distance between the radar array and the drone's center increases the headwind moment, potentially causing the drone to capsize. Therefore, improvements are needed for existing radar-equipped drones. Summary of the Invention
