摘要
针对民用机场净空管理过程中锥形面范围难以准确确定,主要采用手工方式绘制障碍物限制面图进行管理的问题,给出了净空管理过程中受城市建设影响较大的、形状最为复杂的锥形面范围,导出了锥形面边界的计算方法,并确定了围限锥形面的各关键点坐标,为采用计算机自动判定障碍物是否落入锥形面奠定了理论基础。
In order to reduce the inaccuracy in measuring the conical surface and in manually drawing obstacles in civil aerodrome clearance protection management, this paper identified the most complex conical surface clearance management which is largely affected by urban construction. It also proposed a calculating method of the conical surface border and identified the coordinates of the key points in conical surface. This work played an important role for automatic identification of obstacles in conical surface by computers.
