摘要
以安徽四创电子股份有限公司和北京市气象局合作研发的3836双线偏振多普勒天气雷达升级后的状态为主要平台,根据双线偏振雷达探测能力的要求,在新一代天气雷达测试方法的基础上,提出了双线偏振雷达的测试方法,并利用太阳回波资料和天线垂直指向探测方法获取的气象回波验证了该方法和雷达的测试结果。测试结果表明,提出的双线偏振雷达的测试方法合理可行;偏振参数的测试结果表明,3836雷达探测精度能基本满足双线偏振雷达探测降水和识别粒子系统的需求。
Based on the measurement methods of China new generation radar（CINRAD）, the measurement method of dual-polarization weather radar（DPR） is provided according to its detection ability with the 3836 dual-polarization weather radar in Beijing Meteorological Bureau which is provided by Anhui Sun-Create Elec- tronics Corporation Ltd. The echo data of the sun and the meteorology are also used to analyze the measure- ment results. The results show that the presented measurement method are reasonable, and the performance ability of 3836 radar can meet the accuracy of using DPR to detect rainfall and classify hydrometeorology.
