| 摘 要： | 对不同天气情况的资料分别采用单仰角VAD方法和多仰角VAD方法进行风场反演，比较了这两种算法的反演结果，提出了融合两种方法优点的自适应仰角取样方法，并进行反演比较，结果表明：单仰角和多仰角策略各有所长，采用自适应仰角取样策略结合两种方法优点，在某些场合下可以获得更有参考价值的VAD反演结果。 |

| Abstract: | The wind retrieval of the single-Doppler radar data under different weather conditions is performed using the single-elevation and multi-elevation VAD techniques, and the results are compared. On the basis of the comparison, this paper puts forth the selfadapting elevation VAD method, which combines merits of the above techniques. It is shown from retrieval results that the former two methods have their own merits and demerits ,while the selfadapting elevation VAD method is able to get more valuable information on some occassions. |
| Keywords: | VAD technique wind retrieval selfadapting elevation VAD technique Doppler weather radar |
