Threat Level Assessment Based on Fuzzy Bayesian Networks
Aiming at the uncertainty of Threat Level Assessment (TLA) data sources under modern complex battlefielda fuzzy Bayesian network TLA method was proposed by integrating the fuzzy set theory into Bayesian networks.After well considering about the effect of the distance and azimuth angle of threat sources relative to a UCAV on its stealth capabilitythe threat level was evaluated by integrating such uncertain factors as weatherthreat typedistance and azimuth angle based on randomization of uncercain knowledge.Then a TLA Bayesian network was established by adopting Netica software of the Norsys Software Company in Canadaand simulation was carried out.The simulation results show that the method can assess the threat level rapidly and accurately.
