Integrated decision-making method for fire and electronic warfare is studied on the cooperative multi-target attack-defense campaign.A radar detection weaken factor was defined to scale the target threats decrease under electronic jamming attack.To optimize the total threat reduction,cooperative active self-defense jamming power allocation model was established and it is solved using greedy algorithm.Considering jamming effectiveness,target assignment method based on cooperative attack-defense was improved finally.Simulation results showed that the decision process is effective.
