隐身飞机随队干扰对雷达探测性能的影响
|
摘要
针对现有评估方法没有考虑隐身性能与电子战能力有效结合对雷达探测性能产生影响的问题,提出了基于隐身飞机随队干扰的雷达探测性能评估方法。该方法建立了平飞和转弯航迹相结合的隐身飞机随队干扰模型,在经过飞机敏感性分析、航迹参数设定和坐标系转换后,对飞机视线姿态角进行了解算;然后利用隐身飞机全空域的静态RCS数据,仿真得到了时变的动态RCS序列;最后依据雷达探测距离方程和探测概率公式,在确保隐身飞机满足编队飞行的距离和概率条件后,比较研究了目标机在有无干扰两种状态下,雷达探测距离和瞬时探测概率的时变特点。仿真分析表明,隐身飞机随队干扰能够缩减探测距离、减小探测概率,降低雷达探测性能,提升目标机的突防生存力。
Aimed at the problem that the existing evaluation methods of radar detection performance are shortage of considering combining stealth performance and the probability of electronic warfare,the method based on escort-support jamming of stealth aircraft was proposed.The track model of escort-support jamming of stealth aircraft was established based on level flight and turning track,after analyzing aircraft susceptivity,setting trajectory parameter and converting coordinate system,attitude angle to the line of aircraft was calculated.Then the time-varying dynamic RCS series was simulated utilizing all airspace static RCS of stealth aircraft.Finally,according to detection range equation and detection probability formula of radar,after ensuring the formation flight distance and probability conditions of stealth aircraft,the time-varying radar detection range and the instantaneous detection probabilities of radar were compared and studied when target aircraft would be in interference condition and noninterference condition.Simulation and analysis show that escort-support jamming of stealth aircraft could reduce detection range and detection probability,decline radar detection performance,and promote penetration survivability of target aircraft.
