摘　　要：为了改善风廓线雷达观测数据的质量,减少因个别波束测量时被污染而对计算结果造成的误差,提出了进行5波束联合校验计算风的方法。该方法利用风廓线雷达5波束测量数据之间的相关性,根据风廓线雷达5个波束测量值是否通过一致性检查的不同情况进行风的计算。给出了详细的计算流程,并以气球测风结果为参照,对3波束计算法和5波束校验计算法的效果进行了实例对比,结果表明5波束校验计算方法提高了数据的准确性,计算结果与气球测量值之间的误差小,并且在实际工作中已经得到了成功的应用。To improve the quality of wind profiler data, and reduce the error induced by some or other beam＇s data contaminated by clutter, a method using five beams to checkout calculate wind was presen- ted. This method, based on the relationship among the beams, makes use of different formula to calculate wind in different circumstances whether the radar data pass consistency check or not. A detailed algorithm was given. And then, using the wind data observed by balloon as a reference, the effect was compared between this method and the three beams calculate wind method. The result shows that the five beams checkout method can get a higher accuracy with fewer error. The method is successfully applied.
