摘要:: 为明确毫米波雷达在雾的探测方面的能力和作用,利用已有的不同类型雾滴谱模型,估算雷达回波反射率因子范围,其理论值介于-46.31～-3.79 dBZ。利用2019年10-11月宁夏的雾滴谱仪观测数据,估算的回波反射率因子平均值为-19.05 dBZ,最小值为-36.19 dBZ,最大值为-4.73 dBZ。基于上述数据,提出毫米波雷达测雾所需的最小可探测强度等关键性能指标。通过分析714KaDP型毫米波雷达的理论参数,结合昆明和成都两地架设的同型号雷达对雾过程的观测结果,表明该型雷达在适当配置工作参数时,能够有效用于雾的探测。

Abstract:: Millimeter-wave radar has the advantages of strong penetration and high spatiotemporal resolution.While its application to cloud measurement has been extensively researched and tested,its potential for fog measurement has been less explored.This paper investigates the droplet size distribution models of different types of fog and estimates echo intensity values ranging from -46.31 dBZ to -3.79 dBZ.Based on the observation data from a fog droplet spectrometer in Ningxia from October 31^st to November 2^nd,2019,the estimated echo intensity has an average of -19.05 dBZ,with a minimum of -36.19 dBZ and a maximum of -4.73 dBZ.This paper proposes the minimum detectable intensity required for millimeter-wave radar fog measurement and other indicators.Furthermore,it analyzes the theoretical and measured parameters of the 714 KaDP millimeter-wave radar.Results show that this type of radar can be used for fog measurement using the same type of millimeter-wave radar installed in Kunming and Chengdu to observe fog processes when appropriate operating parameters are selected.
