增程型L波段风廓线雷达探测性能分析

Detection Performance Analysis of Range-extended L Band Wind Profile Radar

风廓线雷达作为一种新型的大气风场探测设备，具有时间分辨率高、连续性和实时性好等特点，已广泛应用到各行业。文中首先分析了增程型L波段风廓线雷达的探测能力，简要介绍了该雷达的系统设计；然后，利用中国气象局海口站业务运行一年的观测数据，从探测高度和数据准确率等方面对雷达探测性能进行了统计分析。结果表明：增程型L波段风廓线雷达满足设计指标要求，可用于低对流层大气风场的观测。

Wind profile radar is a new type of atmospheric wind detection device, with the characteristics of high time resolution, continuity and good real-time performance, which has been widely used in various industries. The paper analyses the detection per- formance of range-extended L band wind profile radar, introduces the system design of the radar, and analyses the detection height and data accuracy by using nearly one year data in the Haikou station of China Meteorological Administration. The results show that the range-extended L band wind profile radar meets the design requirements, and can be used for detecting the atmospheric wind in the lower troposphere.
