| 摘 要： | 对雷达测风的风向、风速误差传递函数的准确式和近似式进行了比较分析，指出了近似式的适用范围和修正方法。应用这两个近似式对不同精度雷达进行的计算表明，701雷达在一个相当大的范围内达不到WMO的测定风向、风速精度的要求；若将雷达精度提高到0.12°、20 m，则可基本满足要求；对更高要求的用户，使用0.06°、10m精度的一次雷达是合适的。

| Abstract: | The comparison between the accurate and the approximate expressions of transfer functions of the wind speed and direction errors with balloon coordinate errors sounded by radar is conducted. The suitable range of approximate expression and its correction method are given. The results show that the 701 type radar can not meet in a certain scope the requirement given by WMO about the accuracy of upper wind vector. If the accuracy of angle–measurement is risen to 0.12o, and the accuracy of distance-measurement to 20m, the WMO’s requirement can be basically reached. It is appropriate to use the 5cm or 3cm radar with angle accuracy 0.06o and distance accuracy 10m for some users. |
