摘　　要：机场净空保护区涉及机场安全,其范围内障碍物的高度不得超过机场限高要求,机场在规划建设时,应对机场周边区域障碍物进行测量;机场净空保护区内新建项目,也需要测量,并计算其空间信息。根据障碍物空间信息的测量内容和计算原理,开发了通用机场障碍物计算系统,对外业测量的障碍物成果数据进行处理,计算障碍物的磁方位角、距离、遮蔽角等信息,实现了快速计算和成果输出。The airport clearance protection zone involves airport safety,and the height of obstacles within its scope shall not exceed the height limit of the airport.During the planning and construction of the airport,the obstacles around the airport shall be measured.For new projects in the airport clearance protection zone,it is also necessary to measure and calculate their spatial information.According to the measurement contents and calculation principle of obstacle spatial information,a general airport obstacle calculation system is developed to process the obstacle result data measured in the field,calculate the information such as magnetic azimuth,distance and shielding angle of obstacles,and realize rapid calculation and output of results.
