摘要

将采用定向天线的高空长航时无人机（HALE-UAV

high-altitude long-durance unmanned aerial vehicle）和长方体形状的空中走廊作为研究对象，覆盖策略的基本思想是提取运动球顶椎体的不变覆盖区域——圆柱体，作为基本覆盖单元填充空中走廊；总体目标是在满足圆柱体的高大于空中走廊高度的条件下，使用尽可能少的HALE-UAV。采用几何方法分析了 HALE-UAV 两种典型的运动轨道——圆形和三角形轨道，得到了圆柱体底面半径和高的数学表达式。通过最优化理论比较两种覆盖策略，得到了最优覆盖方案。研究结果表明，圆形轨道总体优于三角形轨道；最优方案是采用准静态浮空平台，次优方案是采用半径较小的圆形轨道，或边长较小的三角形轨道，同时单个轨道上布设一个HALE-UAV。

Abstract

The high-altitude long-durance unmanned aerial vehicle (HALE-UAV) equipped with directional antenna and the cuboid-shaped air corridor (AC) were taken as the study objects

and the basic idea was to extract the invariant coverage area of moving spherical cones

cylinder

as the basic component to fill AC.The general goal was to employ HALE-UAV as few as possible under the condition that the height of the cylinder was larger than that of AC.The circular and triangular orbits of HALE-UAV were analyzed in geometry respectively

and the mathematical expressions of the radius and height of the cylinder were derived.Then two coverage schemes were introduced.Through comparing the two schemes by optimization theory

the optimal coverage strategy was derived.Results show that the circular orbit is better than the triangular orbit.Moreover

the optimal solution is to employ the quasi-static floating platforms

and the suboptimal is to adopt the circular orbit of a small radius

or the triangular orbit of a small side

with a HALE-UAV on an orbit.
