| 摘 要： | 随着雷达技术的快速发展及对探测要求的逐步提高，用常规方法计算层风将造成信息的浪费，且结果也不能真正代表所测层的风速，在分析了高空探测常规计算层风不足之处的基础上，提出了采用小波变换计算层风的新方法，通过计算机仿真及实际数据的对比分析。证实了所提方法的有效性和可靠性。

| Abstract: | With the significant development of radar technique and progressive enhancement of detecting requirement, it will waste information and cannot get the real wind fields by using conventional wind measuring method. In this paper, based on the analysis of the shortage of general data processing in upper air measurements, a new method of data processing with wavelet transform is proposed. Via computer simulation and contrast analysis with real data, the practicability and reliability of the method are validated. |
