Abstract

The invention provides an electromagnetic radiation interference resisting method and device for an information link of an unmanned aerial vehicle. The electromagnetic radiation interference resistingmethod comprises the steps that unmanned aerial vehicle electromagnetic parameters and external electromagnetic radiation interference information are obtained, and a first parameter sensitive threshold, a second parameter sensitive threshold and a third parameter sensitive threshold are generated according to electromagnetic radiation sensitive information; an early warning signal is generated if the current interference signal intensity is greater than a first interference signal intensity threshold and less than a second interference signal intensity threshold; the unmanned aerial vehicleautomatically switches the channel if the current interference signal intensity is greater than the second interference signal intensity threshold and less than a third interference signal intensity threshold; and the unmanned aerial vehicle automatically executes a return instruction if the current interference signal intensity is greater than the third interference signal intensity threshold. According to the invention, the unmanned aerial vehicle can be avoided from being trapped in a strong electromagnetic interference area suddenly or having a sudden unexpected situation, the electromagnetic threat perception ability of the unmanned aerial vehicle is improved, the degree of influences imposed on unmanned aerial vehicle equipment by external continuous wave in-band electromagnetic radiation interference is reduced, and the intelligent development level of the equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an anti-electromagnetic radiation interference method and device for an information link of an unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aerial vehicle controlled by radio remote control equipment or its own preset program. UAV relies heavily on information links. The ground control station sends mission instructions to UAV through uplink data link. UAV After receiving and executing the mission, it transmits telemetry and reconnaissance information to the ground control station through the downlink data link. The data link system includes antenna equipment, receiving and transmitting devices, and terminals. The antenna is the main coupling path for introducing external electromagnetic radiation interference, which makes the data link system an electromagnetically weak link for UAVs. The safety and reliability of UAV eq...
