Considering the difficulty in determining the Basic Probability Assignment Function(BPAF)in the application of evidence theory in naval battlefield situation assessment,a new method of evidence combination based on neural network acquisition probability assignment function is proposed.Firstly,the state,properties,categories and events of the probe target are extracted based on the sensor detection,0 processing and 1 processing.Secondly,the intentions of the enemy target are classified and identified with BP neural network after the pretreatment.Finally the outputs of the neural network are as the basic probability assignment.D-S evidence theory is used to complete the decision level fusion to estimate the battlefield situation.In simulations,the result shows that the method is an effective and feasible method for naval battlefield situation assessment.
