摘　　要：采用VAP(Velocity Azimuth Processing)方法反演多普勒雷达风矢量场,在利用各个距离圈径向速度随方位角分布的廓线推算风向和风速的设计中,要求基数据速度资料中没有明显的脉动。介绍了在多普勒天气雷达风场反演设计中,直接将方格法的速度资料处理过程融入到方格法风场反演的过程中,利用距离方格内保持中尺度特性的特点,不改变原始资料的同时保证风场反演的正确性。The VAP method is used to retrieve the Doppler radar wind vector field. During the design of the calculation of the wind direction and intensity by using the distributions of the Doppler velocity on the distance circle, no obvious pulses are needed in the radar base data. The base data disposal is combined with the wind field retrieved method on the square area. This method maintains the characteristics of the sub-synoptic scale on the square area without changing the base data while ensuring the wind field retrieved property.
