突防任务中的单机对多目标干扰决策

Jamming strategy for single plane to multi-target in task of penetration

针对单机多目标的突防任务,提出了包括干扰时机选择、干扰样式选择以及干扰功率分配的干扰决策策略。在给出干扰时机和干扰样式的模型后,重点分析了干扰功率分配的方法,采用贝叶斯推理算法,构建空战威胁等级评估模型,计算出多个目标的不同威胁权值,最终给出基于威胁等级评估的干扰功率分配方法。仿真结果表明,该方法能充分利用有限的干扰资源,有效地降低敌方威胁,提高载机的突防概率。

Aiming at the task of penetration in the case of single plane to multi-target,a jamming strategy including the choice of jamming occasion,the choice of the jamming mode and the jamming power allocation is proposed.After giving the models of jamming occasion and jamming mode,the paper mainly analyzes the method of jamming power allocation,builds the model of threat level evaluation based on the inference algorithm of Bayesian networks,then works out the different threat weights of multi-target and presents the jamming power allocation method based on threat level evaluation finally.The simulation results show that this method can use the limited jamming resources adequately,reduce the hostile threat effectively and increase the penetration probability of parent planes.
