相控阵天气雷达站环境参数计算及评估系统研发

Development of environmental parameter calculation and evaluation system for phased array weather radar station

摘要:

作为S波段新一代天气雷达的重要补充，目前广东省正加快建设X波段双极化相控阵天气雷达。如何更好的做好优化布局提升全网覆盖率和探测能力，站点选择是否科学合理显得尤为重要。本文设计一套全新的基于数字高程DEM的探测环境参数智能分析系统，客观、定量、自动计算探测净空投影面积、净空占总投影面积比例、投影阻挡面积比例、探测净空体积、静锥盲区体积、低空盲区体积、扫描立体空域完备度等，在现场选址时能够1分钟内输出综合分析结果和建议。作为辅助选址系统，已经在广东省26部X波段双极化相控阵天气雷达选址中应用，输出结论对现场选址起到了很好的指导性作用，为雷达系统建设快速提供科学决策依据。

Abstract:

As an important supplement to the S-band new generation weather radar, Guangdong Province has accelerated the construction of X-band dual polarization phased array weather radar. How to better optimize the layout, improve the coverage and detection ability of the whole network, and whether the site selection is scientific and reasonable is particularly important. In this paper, a new intelligent analysis and evaluation system of detection environmental parameters based on digital elevation DEM is designed to objectively, quantitatively and automatically calculate the detection clearance projection area, the proportion of clearance to the total projection area, the proportion of projection blocking area, the detection clearance volume, the static cone blind area volume, the low altitude blind area volume, the scanning three-dimensional airspace integrity, etc, Be able to output the comprehensive evaluation results and suggestions within 1 minute when selecting the site. As an auxiliary site selection system, it has been applied in the site selection of 26 X-band dual polarization phased array weather radars in Guangdong Province. The output conclusion plays a good guiding role in site site selection and provides a scientific decision-making basis for the construction of radar system.
