机载红外诱饵弹效能的信息评估法

Evaluation of Aircraft Infrared Bait Effectiveness Based on Information Criterion

从信息准则出发较为全面地评估了机载红外诱饵弹效能。首先分析了红外诱饵弹被导弹识别情况.即红外诱饵弹对于导弹的可信性,利用库尔巴克散度计算红外诱饵弹产生的干扰信号与真实目标信号的相似度,由此评定干扰信号优劣,并给出最优信号的评估法,其次对红外诱饵弹有效干扰时的干扰效果进行评估,建立了导引头相对于飞机的加权信息熵模型。最后用算例验证了评估模型的正确性、可行性并做了进一步分析。

Based on information criterion,we analysis effectiveness of aircraft IR bait in this paper.First,we consider how to evaluate the scene that IR guide missile identify IR bait.Make use of kullback divergence of information theory, we develop an evaluation model to identified problcm,give a calculated method of the best optimized ]R jamming signal farther.Second we evaluate the effectiveness of IR bait when jamming work is done.An information entropy model of IR missile seeker to aircraft object is developed to evaluate jamming effectiveness.The results in sample show the validi- ty and feasibility of the evaluation model in the end.
