    摘要:

    为定量分析和评估预警机对歼击机的远距引导效能,以远距引导成功概率作为引导效能指标,模拟预警机远距引导歼击机过程并进行分析和建模。将歼击机的远距引导分解为水平引导和垂直引导,按照平行接近法引导规则,建立水平和垂直引导误差分析模型,利用概率分析方法推导了远距引导效能公式,获得预警机引导误差、机载雷达性能、目标机特性等因素与远距引导效能之间的关系。最后以预警机远距引导某型歼击机拦截目标机为例,在载机速度低于超音速目标的场景下,分析了目标进入角、截获距离、天线扫描范围、目标参数测量精度等主要因素对远距引导概率的影响规律,并根据仿真计算结果,分析讨论了在此场景下提高远距引导效能的有效途径。

    Abstract:

    In order to quantitatively analyze and evaluate the longdistance guidance effectiveness of the Early Warning Aircraft steering the fighter, the longdistance guidance successful probability is taken as an index for describing the guidance effectiveness, and a mathematic model is built up based on analyzing the course of the Early Warning Aircraft steering the fighter. And the course of longdistance guidance is divided into level guidance and vertical guidance, error analysis models of the level guidance and the vertical guidance are built up according to the parallel approach guidance rule, and the algorithms for longdistance guidance effectiveness are put forward by using probability analysis method, through the algorithm the relations are acquired between the longdistance guidance effectiveness and some factors such as guidance error, the fighter radar capability and target characteristic. Under the scene of the fighter lower speed than the target, an example of a fighter intercepting a target by the Early Warning Aircraft's longdistance guidance is given to analyze effect rules of primary parameters on longdistance guidance probability, including target enter angle, intercept distances, antenna scan area and target parameters precision. Through simulation the results efficiency approaches are presented for increasing the longdistance guidance effectiveness based on this scene
