根据舰艇编队超视距反导作战的具体技、战术特点以及影响态势评估的相关因素,构建了超视距反导作战态势评估模型。利用基于VBS及D-S证据理论的证据网络模型对所构建的态势评估模型进行推理,并利用Pignistic变换将信度测度转换为概率测度,且引入了一种对证据网络中事件节点进行基本信度分配的方法。仿真结果表明,该方法能够准确地对超视距反导态势进行评估,具备较强的实战应用价值。 According to the specific technical and tactical characteristics of the over-the-horizon anti-missile battle and the relevant factors that influence the assessment of the naval vessel formation, this paper constructs the assessment model of the combat effectiveness of the over-the-horizon anti-missile defense. We use the evidence network model based on VBS and DS evidence theory to reason the constructed situation evaluation model and use the Pignistic transform to convert the reliability measure to the probability measure and introduce a method to assign the basic reliability to the event nodes in the evidence network Methods. The simulation results show that this method can accurately evaluate the anti-missile RPB potential and has strong practical value.
