摘要
以某机场多普勒天气雷达台站为例,充分利用已有测绘成果,将全站仪免棱镜测量、GNSS测量和CASS制图等内外业技术交叉融合运用,结合优化后的内业分析工具和外业调查模式构建出一套以内业为主、外业为辅的机场多普勒气象雷达台站场地环境调查测绘的方法,并利用开发的“遮蔽角和等射束高度图生成”工具对成果图进行了快速绘制,同时对气象雷达台站四周遮挡情况进行了分析。结果表明,本文构建的遮蔽角测绘方法优化了内业数据处理和外业调查模式,提高了工作效率,保证了测绘成果的质量。同时,测定的雷达台站四周障碍物的遮蔽角成果可靠性高,可作为障碍物的限制高度评估、较大障碍物及时拆除和气象台站更新建设的基础数据。
This paper takes a Doppler weather radar station as an example,making the most of the existing surveying and mapping results,the multi-technologies such as super station angle measurement without prism,GNSS measurement,and CASS mapping are integrated,combined with the optimized indoor analysis tools and field investigation mode,a set of site environment survey and mapping method suitable for the airport Doppler weather radar station was built,which is mainly based on the indoor work and supplemented by the outdoor work.Finally,the result map is rapidly produced by using the developed tool of“generation of shielding angle and equal beam height map”,and the shielding situation around the weather radar station is analyzed.The results indicate that the shielding angle surveying method constructed in this article optimizes the indoor data processing and outdoor survey mode,improves work efficiency,and ensures the quality of surveying and mapping results.Practice has proved that the results of obstacle shielding angle measured in this paper are highly reliable and can be used as the basic data for obstacle height limitation evaluation,timely removal of large obstacles,and renewal and construction of meteorological stations.
