Electromagnetic radiation interference resisting method and device for information link of unmanned aerial vehicle

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
