Abstract:

Because the types and working methods of electronic countermeasures are diverse and change rapidly, effective information is difficult to obtain completely, and different operational characteristics are presented in different operational stages, so it is difficult to accurately evaluate their ranking by using traditional evaluation methods. Therefore, a target level evaluation method of electronic countermeasures based on random set dynamic Bayesian network is proposed. Firstly, the generation method of electronic countermeasures combat target list is combed, the evaluation index system is determined, and the evaluation system is improved based on the changing characteristics of the combat stage combined with the dynamic Bayesian network. Then, after fully consider the characteristics of incomplete data acquisition in combat, the traditional method of solving node parameters of Bayesian network is extended through the introduction of the random set method, and the more accurate node parameters of dynamic Bayesian network are obtained by using the idea of interval mathematics. Finally, the simulation calculation and result analysis of an example are carried out, and the complexity of the algorithm is discussed by the method of determining the node probability. The results show that the method proposed in this paper is more suitable for military evaluation with incomplete samples, and the evaluation results are basically consistent with actual combat situation. The algorithm used are efficient, applicable and popular.
