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。
Aiming at the application of tactics of stealth aircraft, the effects of tactical maneuvering on dynamic RCS and dynamic target detection are discussed. Firstly, the shape of a typical stealthy aircraft is electromagnetically modeled and the static RCS of its whole airspace is calculated. Then the relationship between the maneuvering flight and the line of sight of the radar is studied respectively from three aspects: pitch, yaw and roll. Finally, a target detection Probabilistic mathematical model is used to simulate the influence of stealth aircraft on dynamic RCS sequences and detection probability by using MATLAB programming. The simulation results show that stealth aircraft can significantly change the detection probability when using tactical maneuver. The research provides theoretical and experimental evidences for tactical maneuvering on the stealth aircraft.
