为提高飞行器对地攻击效能,必须对其三维航路规划技术进行研究。通过考虑飞行器姿态变化对暴露范围的影响,建立了飞行器隐身模型;考虑到威胁并非不可穿越,建立了间歇式暴露模型;针对在改进稀疏A*算法的基础上发展的分步规划算法存在规划局部收敛的缺陷,提出了一种基于分级策略的三维航路规划方法;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, its 3D route planning technology must be studied. The aircraft stealth model 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 non-transitory. A partial planning algorithm based on the improved sparse A * algorithm was proposed Aiming at the shortcomings of convergence and convergence, a three-dimensional route planning method based on grading strategy is proposed. Finally, simulation is carried out under the real terrain. The results show the validity and practicability of the proposed model and algorithm.
