摘要
通过对航空器冲突判定模型的研究,阐述了两种模型的构建方式和具体应用方法,基于两种模型的建模方式和算法特点提出了一种新的冲突判定模型,新的模型简化飞行态势的分类和航空器保护区的设定,以航行差、航空器相对趋势及告警距离为主要影响因素,通过MATLAB利用雷达历史数据对新构建的模型进行了仿真验证,结果证明此模型在一定程度上提高了冲突探测的准确性,并满足实时性和虚警率的最低要求,保障了航空器的安全高效运行。
Through the study of aircraft conflict decision model,this paper expounds the way of two kinds of model building and concrete application method,feature modeling method based on two kinds of models and algorithm proposed a new conflict decision model,simplifying the classification of flight dynamics and spacecraft reserve set,with poor navigation,aircraft relative to trend,warning distance as the main influence factors,by using MATLAB radar historical data to the new building has carried on the simulation model,the results prove that model in a certain extent,improve the accuracy of the conflict detection,and meet the minimum requirement of real-time and false alarm rate,guarantee the safe and efficient operation of the aircraft.
