针对无人作战飞机(UCAV)对地自主攻击作战效能不高的问题,设计了一种基于任务成功率的自主攻击方法。在分别建立UCAV和制导炸弹数学模型的基础上通过横向机动控制UCAV暴露的RCS,设计了最优攻击轨迹,采用模式搜索法得到制导炸弹投放域并据此设计了二次投弹过程。运用马尔柯夫理论动态模拟自主攻击过程对自主攻击方法进行了效能评估。仿真结果表明,攻击轨迹与投弹方式相互关联,不同的攻击轨迹需采用相应的投弹方式以提高整体作战效能。

In view of combat effectiveness of air-to-ground autonomous attack for unmanned combat aerial vehicles (UCAV), an approach of autonomous attack based on succeed probability of assignment was proposed. Based on mathematic models of UCAV and guided bomb the exposed RCS of UCAV was controlled by lateral weaving maneuver with what the optimal attacking trajectory was designed. Through the pattern search algorithm, launch region was calculated and the way how to make another chance to release guided bomb was indicated. Via-ble autonomous attacking strategy was simulated through the analysis of combat effectiveness by the method of Markov dynamic simulating theory. The simulation result demonstrates that attacking trajectory is associated with the release mode of guided bomb. To increase the whole combat effectiveness, different attacking trajectories need corresponding release modes.
