The invention relates to a ground multibeam electric controlled scanning measuring and controlling antenna for an unmanned aerial vehicle, which comprises the components of a horizontal low-elevation-angle electric-control multibeam high-gain directional antenna array, a large-elevation-angle beamforming omnidirecitonal antenna and an RF switch array which is controlled by a wave beam for connecting. The invention aims at a technical gap in measuring and controlling by a multiple-target unmanned aerial vehicle and provides a technical solution in which an electric controlled multibeam scanning antenna system is used for supplying semi-space wavebeam whole coverage and performing tracking, measuring and controlling on the multiple-target unmanned aerial vehicle. For saving cost, considering the performance and reducing system complexity, the RF switches are used for performing electric control scanning on multiple beams which cover the low-elevation-angle area antenna array and the omnidirectional antenna that performs overhead large-elevation-angle beamforming, thereby realizing tracking, measuring and controlling on the multiple-target unmanned aerial vehicle.
