为提高飞行器对地攻击效能,必须对其三维航迹规划技术进行研究。通过考虑飞行器姿态变化对暴露范围的影响,建立了飞行器简化RCS模型;考虑到威胁并非不可穿越,建立了间歇式暴露模型;在改进稀疏A*算法的基础上提出了一种具有实时规划能力的分步规划算法,针对该算法存在规划“死胡同”的缺陷,提出了一种具有预测能力的三维航迹规划方法;最后,在真实地形下进行了仿真验证,结果表明所建模型及算法的有效性和实用性。
In order to improve the effectiveness of aircraft attack on the ground, we must study its 3D trajectory planning technology. The RCS model of the aircraft was established by considering the impact of aircraft attitude changes on the exposure range. An intermittent exposure model was established considering that the threat was not impossible to pass. Based on the improved sparse A * algorithm, a real-time planning capability Aiming at the flaw of “dead end” in planning algorithm, this paper proposed a three-dimensional trajectory planning method with predictive ability. Finally, the simulation was carried out under the real terrain. The results show that the proposed model and algorithm Effectiveness and practicality.
