【摘要】：研究三维空间中无人机飞行紧急避撞目标区检测问题,可提高无人机飞行安全水平。当前的飞行避撞目标区静态检测方法对空域利用不足,而动态检测方法只是在水平面内进行理论推导验证而致使实用性较低。针对上述问题,提出了基于无人机三维空间机动轨迹的紧急避撞目标区检测方法,根据无人机自身的机动能力,采用航空器质点动力学与运动学方程,解算出三维空间中无人机机动轨迹。结合入侵机飞行信息构建两机距离函数,并检测出避撞成功时入侵机距无人机的最近位置,建立避撞目标区包络。仿真计算结果表明了改进方法的有效性,提高了空域利用率,同时具有较高实用性。
[Abstract]:UAV flight collision avoidance target detection problems in three-dimensional space, can improve the safety level of the UAV flight. Flight collision avoidance target detection method using the static and dynamic detection method of airspace, only in the horizontal plane is deduced. The practical verification is low. To solve the above problems, put forward the collision avoidance target detection method of UAV maneuvering trajectory based on three-dimensional space, according to the mobility of the unmanned helicopter, the aircraft particle dynamics and kinematics equation, the solution of UAV machine moving trajectory calculated in three-dimensional space. Combined with the flight information to construct two machine distance function, and detect the collision position recently successful invasion machine from the UAV, a collision avoidance target envelope. The simulation results show that the improved method is effective, improve the airspace utilization, at the same time, it is of high practical .
