Secret-related place interference shielding method and system based on unmanned aerial vehicle communication

The invention relates to a secret-related place interference shielding method and system based on unmanned aerial vehicle communication. The method comprises the following steps: transmitting a friendly signal to a secret-related place through an unmanned aerial vehicle in an unmanned aerial vehicle communication system, wherein the friendly signal is a signal in a set frequency range; according to the initial friendly signal power emitted by each unmanned aerial vehicle, determining the coverage probability of the friendly signal in the secret-related place; on the basis of an improved particle swarm algorithm, adjusting the friendly signal power emitted by each unmanned aerial vehicle by taking minimization of energy loss as a constraint condition, and determining the final friendly signal power emitted by each unmanned aerial vehicle by taking maximization of coverage probability as an optimization target; according to the improved particle swarm algorithm, adding a set disturbance value in particle speed
