A method of cooperative interference resource allocation based on improved butterfly optimization algorithm

Aiming at the problem of radar interference resource management decision under cooperative confrontation,a method of interference resource allocation based on the improved butterfly optimization algorithm is proposed.Firstly,fuzzy comprehensive evaluation method is used to quantify the factors that affect the threat level and jamming effectiveness of radiation sources.Then,the jamming resource allocation model is established on the basis of determining the objective function and calculating the jamming effectiveness matrix. Finally, the adaptive heuristics and inferior solution acception operation are introduced into the butterfly optimization algorithm (BOA) to solve the model.Simulation results show that the introduction of the improved terms improves the exploration ability and search efficiency of BOA,and effectively solves the local convergence defects of the algorithm.In addition,the proposed algorithm is superior to four kinds of classical algorithms and two kinds of improved BOAs in convergence accuracy and stability,and the developed interference resource allocation scheme is more reliable.
