不同导航方式无人机侦察效能比较研究

Comparison of UAV Reconnaissance Effectiveness under Different Navigation Methods

无人机对目标进行侦察是无人机作战使用的主要模式之一,无人机侦察能力除与机载侦察设备有关外,机载导航设备对侦察效能也有很大的影响。为此,以CCD摄像机为机载侦察设备,研究了一种基于完成任务能力和飞行代价函数的无人机侦察效能评估模型,并对不同导航方式、不同干扰强度条件下,无人机对给定区域的侦察效能进行了评估,得到了不同导航方式对无人机侦察效能的评价曲线,为根据无人机的使命任务选择导航方式提供了决策依据。

As UAV mainly works for reconnaissance,its reconnaissance ability is effected not only by airborne reconnaissance equipment but by airborne navigation equipment.Taking a CCD camera as airborne reconnaissance equipment,a effectiveness evaluation model for UAV reconnaissance based on mission achievement ability and flight cost is studied.Furthermore,UAV reconnaissance effectiveness of given area is evaluated under different navigation method and different interference intensity,and the evaluation curve is attained,which provides a decision foundation of the choice of navigation methods for UAV mission.
