【摘要】：考虑到机场周围障碍物对飞行安全的影响,文章提出一种基于World Wind的障碍物评估方法。该方法根据机场环境和飞行程序设计要求建立OAS面数学模型,对给定的数据进行分析计算;对World Wind进行二次开发,实现障碍物与OAS面关系的三维可视化,结合客观数据分析和三维仿真结果给出评估报告;并分析障碍物对导航信号遮蔽影响,完成对障碍物的进一步评估。通过对天津机场障碍物验证分析表明,该方法对障碍物评估计算结果与ICAO使用的专业软件结果一致,并且更便捷直观,同时通过研究障碍物对某DME台信号的遮挡影响,结果证明能够准确地计算DME信号近距有效覆盖范围。
[Abstract]:In view of the influence of the obstacle around the airport on the flight safety, an obstacle assessment method based on World Wind is proposed. according to the requirements of the airport environment and the flight program design, an OAS surface mathematical model is established, the given data is analyzed and calculated, the three-dimensional visualization of the relationship between the obstacle and the OAS surface is realized through the secondary development of the World Wind, and the evaluation report is given in combination with the objective data analysis and the three-dimensional simulation result; And the influence of the obstacle on the shielding effect of the navigation signal is analyzed, and further evaluation of the obstacle is completed. The analysis of the obstacle of Tianjin airport shows that this method is consistent with the professional software results used by ICAO, and it is more convenient and intuitive, and at the same time, by studying the blocking effect of the obstacle on the signal of a certain DME station, The results show that the DME signal near-range effective coverage can be accurately calculated.
