Since the Computer Generated Force (CGF) can not take full advantage of battlefield information to optimize CGF submarine search strategy in the cooperative antisubmarine combatthe information fusion technology was introduced into the antisubmarine warfare simulation based on the effective interaction of the information between CGF.The basic confidence assignment of the evidence information was obtained using Back Propagation (BP) artificial neural networkand the information from antisubmarine CGF was synthesized by using the improved DS evidence theory.And thus the antisubmarine CGF mobile strategy was improved.Simulation results show that the introduction of artificial neural network and information fusion technology in antisubmarine CGF submarine search process can improve the antisubmarine efficiency.
