摘要
针对中距空战接敌过程中载机容易受敌方中距导弹攻击的问题,提出一种利用机载脉冲多普勒雷达探测盲区实现隐蔽接敌的机动决策方法。该方法首先建立当前态势下敌机雷达多普勒盲区模型,并利用电子支援措施(ESM)对辐射源的量测信息生成安全飞行边界,然后对3种ESM战术状态分别建立机动决策模型,最后通过滚动时域控制(RHC)算法求解接敌过程中的最优机动策略。仿真结果证明,优化后的接敌轨迹可有效降低载机被发现和跟踪的概率,并取得较为明显的态势优势。
A decision-making model was established for preventing the fighter from being attacked in the medium and long distance air get close to. The model helps the fighter get close to the enemy in stealth way by making use of the Doppler blind zone of the enemy＇s Pulse Doppler（ PD） radar. Firstly the Doppler blind zone model of the radar onboard enemy fighter is established. Secondly,the safe boundary is settled with the support of Electronic Support Measures（ ESM）. Then,three decision-making modes are established and switched according to the states of ESM states. Finally,an optimal maneuver strategy is figured out by the Receding Horizon Control（ RHC） algorithm. The experiment turned out that a fighter can accomplish a lower risk of being detected and tracked if adopting the optimal maneuver strategy,and finally get better superiority on situation.
