摘　　要：近年来 ,雷达在风场探测领域起了越来越重要的作用 ,与传统的放气球的测风方法相比 ,它具有方便、经济、实时性好、可以连续观测等优点。本文讨论了分布天线机制测风雷达的全相关分析方法的原理 ,并用C语言编写了全相关分析方法的程序 ,得到了大气水平风场 ,与武汉中频雷达原装软件的分析数据进行了比对 。In recent years, radar is gradually applied to wind field measurement. Compared with traditional wind measurement methods, radar have many good qualities, such as convenience, economy, good real-time quality, it also can realize continuously measuring. Just for these good qualities, radar is being applied more and more widely. In this paper, a simple method of analyzing atmospheric wind field of Spaced Antenna wind radar, the Full Correlation Analysis Method is introduced in detail. Based on this method, we have coded a set of Spaced Antenna wind radar date processing procedures by C language and used it to calculate the true wind velocity. The result of comparing our calculated wind velocities with original software calculated wind velocities is also presented in this paper, which shows that both of them are consistent.
