Problems solved by technology

However, if radar and photoelectric detection equipment are widely installed in the civilian field, there will be problems such as small coverage of individual equipment, high construction costs, and no network coverage, etc., which will greatly limit the widespread popularization of aerial equipment such as drones.
The mainstream infrared / visible light monitoring system has a small coverage area. If it cannot be properly deployed, it is very likely that there will be a detection blind spot, which will cause the problem of inability to locate or inaccurate positioning.

Abstract

The invention discloses an unmanned aerial vehicle detection method. A location functional unit and a directional antenna used for transceiving a signal in a low altitude range are added in each basestation of a wireless communication system. The method comprises the following steps: transmitting a locating signal used for the unmanned aerial vehicle detection to low altitude by the directional antenna in any base station in the system; receiving the locating signal, reflected by an unmanned aerial vehicle, by the directional antenna of the any base station or other base stations; and detecting according to the received locating signal by the location functional unit of the base station receiving the locating signal reflected by the unmanned aerial machine, and locating the unmanned aerial vehicle. By applying the method disclosed by the invention, the unmanned aerial vehicle detection can be conveniently realized, coverage can be guaranteed, and location accuracy is improved.

Description

technical field [0001] The present application relates to UAV technology, in particular to a UAV detection method and base station equipment. Background technique [0002] In recent years, the demand for airspace development and utilization has gradually increased, such as the application of aerial flying objects represented by drones in low altitudes in aerial photography, logistics, live events and other fields. In practical applications, most UAVs are equipped with sensors such as cameras and infrared sensors, which enhances their intelligence and automation, and enhances the flexibility of UAVs from space and geographical restrictions. However, this inevitably brings security problems, such as affecting the aviation order, breaking into sensitive areas, etc. Therefore, it is necessary to conduct inspections on the flying objects in the surrounding areas in important venues such as government buildings, military bases, communication hubs and large-scale event sites. Prob...
