摘要
针对隐身飞机机动战术的应用问题,讨论了战术机动飞行对动态RCS以及动态目标检测的影响。首先对某典型隐身飞机的外形进行了电磁建模,计算其全空域静态RCS,接着分别从俯仰、偏航以及滚转三个方面研究了机动飞行与雷达视线角的关系,最后建立了目标检测概率数学计算模型,利用MATLAB编程仿真了隐身飞机采取不同机动后对动态RCS序列及检测概率的影响,仿真结果表明隐身飞机采用战术机动时能够显著改变检测概率。该研究为隐身飞机采取战术机动突防手段提供了仿真理论和实验依据。
In view of stealth aircraft tactical maneuver application problem, this paper discusses the influence of tacti- cal maneuver on dynamic RCS and target detection. First, establish the EM model of a typical stealth target, and obtain stat- ic RCS of full airspace; Then analyze from three aspects of pitch, yaw and rolling the relationship between tactical maneuver and the line of sight of radar; Finally, establish the detection probability calculation model, and simulate the influence on dy- namic RCS series and detection probability by MATLAB when different tactical maneuver is adopted by stealth aircraft. The simulation results show: detection probability of the stealth aircraft changes effectively after tactical maneuver is used. This study provides simulation theory and experimental evidence for application of stealth aircraft tactical maneuver.
