Multi-domain battlefield threat assessment based on D-S evidence theory and conditional probability table

With the development of information technology, the scope of battlefield is more and more extensive, and multi-domain Defensive operations are getting more and more attention. In order to improve the accuracy of multi-domain battlefield threat assessment, so as to deploy troops scientifically for effective defense, the probabilities of attacks occurring in each regional battlefield are calculated by D-S evidence theory, and then the probabilities of attacks succeeding are calculated by using conditional probability table when attacks are occurring in corresponding area. The probabilities of attacks succeeding are used to assess regional battlefield threat. On the basis of regional battlefield threat, the entire battlefield threat is calculated by combining regional weight. Finally, the results of case show that the proposed method is in line with the actual situation and the assessment results are accurate and effective.
