摘要
三维空间路径规划在某些特殊情况下必不可少,如无人战斗机为了降低敌雷达的探测概率,利用山谷或其他特殊地形飞行。在原有基于平面Vorinio图的路径规划基础上,将Voronoi图的概念进行了推广,提出了“空间改进型Voronoi图”的概念。研究了不同威胁体下“空间改进型Voronoi图”构图的一些基本原则,包括不同威胁体下“空间改进型Voronoi图”作图法,以及突发威胁体下空间局部路径重规划区域原则和空间局部最优路径选择原则等。并将平面路径规划下无人战斗机战场态势感知模型推广到三维空间。仿真结果表明整个模型构架的基本思路可行。
Path Layout of UCAV on plane has achieved many conclusion.However,path layout of UCAV in Space is useful to special instance.For example,UCAV fly in valley to reduce probability to be detected by radars of enemy.It is necessary for UCAV to do path layout in space.The paper brings out some base principle about composition of a picture for path layout in space,including improved Voronoi base on different threater in space,a principle area of renew layout of local path,and way to choose a optimiz path of renew layout of local path etc,and obtain some useful conclusion.At the same time,we spread UCAV apperceive models of plane to space too.At the end,the emulational experiment proves that the idea is right.
