The invention relates to a malicious interference-oriented unmanned aerial vehicle group dynamic spectrum allocation method and system, and relates to the field of unmanned aerial vehicle electromagnetic spectrum allocation, and the method comprises the steps: initializing the channel selection probability of a jammer, and carrying out the channel selection according to the channel selection probability of a current period; initializing an unmanned aerial vehicle user channel allocation probability, and performing channel allocation according to the channel allocation probability of the current time slot tau; calculating own utility; updating the channel allocation probability of the tau + 1 time slot; judging whether the unmanned aerial vehicle user is stable or not, if so, ending, and otherwise, returning to the step of performing channel allocation by the unmanned aerial vehicle according to the channel allocation probability of the current time slot tau; the jammer updates the Q value according to the benefit function; the jammer updates the channel selection probability according to the Boltzmann distribution rule; and when the channel selection probability pJ (t + 1) of the jammer is equal to pJ (t) or the maximum number of iterations is reached, ending. According to the method, the dynamic spectrum allocation of the unmanned aerial vehicle group can be realized under the malicious interference condition.
Description
technical field [0001] The invention relates to the field of electromagnetic spectrum allocation of unmanned aerial vehicles, in particular to a method and system for dynamic frequency spectrum allocation of unmanned aerial vehicle groups oriented to malicious interference. Background technique [0002] With the rapid development of the world's new military revolution and high-tech, as a new type of combat force, UAVs are gradually applied to reconnaissance and surveillance, electronic countermeasures, and fire strikes due to their strong mobility, high concealment, and low manufacturing costs. , communication command and other tasks. On the one hand, because UAVs usually perform tasks in large-scale fleets, a large number of UAVs access the frequency band of the mission area at the same time, which causes the frequency band to become more and more crowded; at the same time, there may also be interference between multiple users in a channel, and spectrum resources are in sho...
