A Intelligence Target Situation Assessment Method for Cooperative Search by ASW Patrol Aircraft

To handle the problem of target situation assessment with a large amount of uncertain information in naval battlefield, Bayesian network and cloud theory are introduced, and a method of situation assessment for ASW patrol aircraft cooperative search potential target in autonomous mode based on cloud Bayesian network is presented. In this method, the cooperative search schemes of autonomous mode and lead-wing mode for ASW patrol aircraft are established. And based on autonomous mode, the target situation assessment model based on cloud Bayesian network is designed, and Bayesian network structure which is the directed acyclic graph is constituted. Then, the indexes of target situation assessment are delineated. After that, the cloud model is adopted to discretize the model. And. the conditional probability table(CPT) for each node are calculated as well. At last, the target type and the other side's fighting intention are inferred, and the battlefield situation is formed. The simulation is combined with the problem analysis process, and the method is feasible from the simulation results, what's more, it will have the desired effect.
