In the process of ASW patrol aircraft cooperative search target, there is a lot of uncertainty in situation evaluation problem. In order to deal with the uncertain information, cloud theory and Bayesian network are introduced, and a method based on cloud Bayesian network is proposed to to deduce the enemy’s operational intention and form the battlefield situation. Firstly, a situation evaluation model of cooperative search target is established. Secondly, the cloud model is used for discretization. After determining the conditional probability table(CPT) of each node and the conversion between certainty and probability, the final situation grade is obtained through the probability composition formula. The simulation results show that the proposed method is reasonable and effective.
