Method of Threat Assessment for Air Defense Fire Control Radar Based on Discrete Fuzzy Dynamic Bayesian Network
Lei Jiude · Modern Radar · 2013
Aiming at threat assessment of the fire control system of the air defense fire control radar,a new threat assessment method is proposed based on the discrete fuzzy dynamic Bayesian network.Firstly,the uncertain data is inferred by the fuzzy theory,so the training and test data of threat assessment model are gained.Then the grade is quantified,and the same characteristic parameter at multiple times can revise and supplement each other in the model,moreover,different characteristic parameters at the same time can revise each other,and threat assessment is carried out to observed values that is at any time or at a certain time,therefore correct results are derived by the inference algorithm of the fuzzy dynamic Bayesian network.Finally,the simulation is carried out,and simulation results show that the method is reasonable and effective.
