Air-to-air antenna parameter configuration method for air-to-ground user coexistence unmanned aerial vehicle network

Abstract

The invention provides an air-to-air antenna parameter configuration method for an air-to-ground user coexistence unmanned aerial vehicle network, and the method comprises the steps: adding an upward inclined special antenna to a ground base station, and providing services for air users. Specifically, an unmanned aerial vehicle user is served by limited sidelobe gain of a base station side antenna in an existing scene, and the unmanned aerial vehicle user can receive more serious interference and seriously influence the performance of the unmanned aerial vehicle compared with a ground user due to the high sight distance propagation probability of the unmanned aerial vehicle user, so that the invention proposes that an air antenna is added to a base station. An antenna inclining upwards on the ground base station side provides service for an unmanned aerial vehicle user, an antenna inclining downwards on the base station side provides service for a ground user, and therefore accumulated interference borne by the user can comprise the interference of the antenna inclining upwards and the interference of the antenna inclining downwards. The user performance change before and after the air antenna is added is analyzed through the change of the coverage probability of the unmanned aerial vehicle user and the ground user, so that the antenna parameter configuration method is determined.

Problems solved by technology

However, since the flying altitude of the drone may be higher than the ground base station, it may be served by the antenna sidelobe or reflected signal of the ground base station when accessing the cellular network, which leads to the performance of the drone user being significantly lower than that of the ground user.
