基于隐身的三维航迹规划研究

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。考虑到威胁并非不可穿越,建立了间歇式暴露模型;通过考虑飞行器姿态变化对暴露范围的影响,建立了飞行器战术隐身模型;对传统稀疏A*算法进行了改进,有效提高了规划速度,在此基础上提出了具有实时规划能力的分步规划算法,并给出了解决在线重规划的方法;最后,在真实地形下进行了仿真验证,仿真结果证明了所建模型及算法的有效性和实用性。

Research on 3D-route planning based on aircraft stealth

In order to improve the attacking efficiency of aircraft,3D-route planning technology must be studied.Firstly,given the problem that threat area can never be passed through being not true,discontinuously exposing model is built.Secondly,by analyzing the effect of aircraft pose changing on the exposing range,the aircraft stealth model is built.Thirdly,quickly planning is realized by improving traditional sparse A-star algorithm,based on which,the step by step plan algorithm is put forward,and at the same time,the re-route planning on-line method is given.At last,simulation is given in real terrain,whose results show that the model and algorithm work perfectly.
