摘要
预警机对战斗机的远距引导效能是预警机作战效能体现的重要环节。为实现对远距引导效能的定量分析与评估,以远距引导成功概率作为效能指标。首先,将远距引导分解为水平与垂直引导,采用平行接近法建立引导误差分析的数学模型。其次,依照航向均方根误差的推导流程,推导得到俯仰角均方根误差的表达式,建立了基于概率分析法的远距引导效能模型。最后通过设置仿真拦截场景,分析了目标截获距离与参数测量精度、拦截速度、搜索空域等参数对远距引导成功概率的影响规律,验证了模型的有效性。
It is importance tache of the early warning aircraft＇s battle effectiveness that to steer fighter in long-dis- tance. In order to quantitatively analyze and evaluate the long-distance guidance effectiveness, long-distance guidance successful probability is given as the index for effectiveness. Firstly, the course of long-distance guidance is divided into horizontal and vertical guidance, and the error analysis models of the horizontal guidance and the vertical guidance are built up according to parallel approach guidance rule. Secondly, according on root mean square error of the course is de rived, the root mean square error of elevation is also obtained through derivation, meanwhile long-distance guidance model is built up based on probability analyze method. Finally, an example of a fighter intercepting a target by the ear- ly warning aircraft＇s long distance guidance is given to analyze effect rules of primary parameters on long-distance guid- ance probability, including target intercep^distance, target parameters measure precision, intercept-speed and antenna scan area. Simulation results prove the effectiveness of the proposed model.
