摘　　要：风廓线雷达用于探测其上空风向、风速等气象要素随高度的变化情况,在自动化程度和探测时空分辨率等方面优势明显,已逐渐广泛应用于机场气象探测。本文以民用机场拟建风廓线雷达遮蔽角的测绘方法和实践为例,介绍如何测定并计算拟建风廓线雷达四周范围内障碍物的遮蔽角,并根据测算遮蔽角值判断障碍物是否对风廓线雷达信号发射造成影响,为申请风廓线雷达正式批复、建设提供基础数据保障。The wind profile radar is used to detect changes in the meteorological elements such as wind direction and wind speed with altitude, and has obvious advantages in terms of automation degree and detection space-time resolution. It has gradually been widely used in airport meteorological detection. Based on the civil airport proposed wind profile radar cover angle mapping method and practice, introduced how to measure and calculate it wind profile radar range of obstacles to cover around the corner, and according to the value of cover angle, determine if the obstacle affects the signal emission of wind profile radar, to apply for wind profile radar provide the basis for a formal approval, construction data security.
