无人战斗机航路规划圆切线算法

通过对无人战斗机低空进入敌防区面临的各种威胁进行分析,建立了适用于圆切线算法的威胁场模型;由于可行方向法对威胁圆叠加时规划出的航路效果不理想,提出了圆的切线算法理论作为此航路规划方法的改进,采用随机产生威胁场的方法来模拟多变的战场环境,并且进行了理论分析,最后得出仿真结果.仿真证明,将两种方法结合规划出的飞行航线在航程上是比较理想的,而且路径规则的效果也得到了很大的提高.

Study on Trajectory Plan Arithmetic for UCAV by Using Tangent to Circles

By analysis of different threaten facing to the Uninhabited Combat Aerial Vehicle(UCAV) during entering into the enemy defense aero at a lower flying height,a threaten field model suitable for tangent to circles arithmetic has been established.Because the trajectory planned by feasible direction method is not ideal in the condition of superposing threaten circles,a tangent to circles arithmetic as an addition to the trajectory programming arithmetic has been introduced.The levity battlefied circum stance has been simulated with random create method.The theory analysis and the simulation results have been given as well.The results show that the flight trajectory planned by the combined arithmetic was more satisfied and the effect has been improved.
