Abstract:	Aiming at scarcity of a frequency spectrum and susceptibility to be jammed of the cognitive satellite terrestrial networks, this paper studies their anti jamming channel selection. Firstly, considering that the ground cognitive users are interfered by many aspects, Stackelberg Game is constructed according to the master slave relationship between the users and the jamming. At the same time, in view of the local influence of the mutual jamming between users, the relationship between the users is constructed as a graph game, and the existence of the above game equilibrium is proved theoretically. Then, in order to obtain an equilibrium solution of the anti jamming channel selection, a hierarchical learning algorithm based on local information interaction is proposed, in which cognitive users not only consider their own throughput, but also consider the throughput of neighbor users, and achieve global optimization through local optimization. Through simulation analysis, the convergence and effectiveness of the proposed algorithm are verified from the experimental level.
