Spectrum allocation method and device under multi-unmanned aerial vehicle network information hidden transmission condition

The invention discloses a frequency spectrum allocation method and device under a multi-unmanned aerial vehicle network information hidden transmission condition, and relates to the technical field of unmanned aerial vehicle communication, and the method comprises the steps: firstly constructing a frequency spectrum allocation model under the multi-unmanned aerial vehicle network information hidden transmission condition; the spectrum allocation model takes maximization of the satisfaction degree of information transmission from the unmanned aerial vehicle to the ground control station as an optimization target, takes routing selection constraint, bandwidth constraint, transmitting power constraint, block length constraint, communication concealment constraint and signal-to-noise ratio constraint as constraint conditions, and then solves the spectrum allocation model to obtain an optimal spectrum allocation scheme; the optimal spectrum allocation scheme comprises an optimal route selection scheme, a bandwidth
