A mathematical model suitable for frequency assignment is built in this paper,in which certain factors affecting the electromagnetic environment are transformed to the constraints,and then the cost function is constructed,to make the elec-tromagnetic environment to be described quantitatively. Hybrid particle swarm optimization algorithm is used to solve the prob-lem of frequency assignment,in which the thought of genetic algorithm is introduced,and natural selection and hybridization means are added in the iterative process. The simulation results indicate that the algorithm converges quickly and has a certain capability to avoid its falling into local optimum.
