地对空干扰条件下作战飞机空中突击效能评估研究

摘要

A method was discussed for effectiveness evaluation of combat aircraft in assaulting fixed ground target under surface-to-air radar jamming. By analyzing the operational process of air assault,and taking the target destruction probability of single aircraft's first assaulting as the effectiveness index, the models for the aircraft's side direction deviating distance and probability of the target in valid searching area were established by use of probability analysis method. The method for calculating the target destruction probability of single aircraft's first assaulting was given. Demonstrations were carried out to prove the validity of the proposedmodel. Finally,the effects of jamming signal's spectrum density and airborne radar's search angle on the target destruction probability and jamming shield angle were obtained, which provides a new way for evaluating operation effectiveness of combat aircraft.%探讨了地对空雷达干扰条件下作战飞机对地面固定目标实施突击时的效能评估方法问题.通过分析空中突击的作战过程,采用概率分析法,以单机首次攻击摧毁目标概率作为效能评估指标,建立了作战飞机进入目标区域时侧向偏离目标距离模型和目标落入机载雷达有效搜索区域概率模型,给出了单机首次攻击摧毁目标概率的计算方法.在此基础上,通过算例对模型中的主要影响因素进行了分析验证,得出了干扰信号频谱密度、机载雷达最大搜索角等参数对单机首次攻击摧毁目标概率、干扰掩护角的影响曲线,为评估飞机作战效能提供了一种新思路.
