Based on the horizontal wind field data of wind profile radar in Yichun of Jiangxi in February and August 2016,the extended empirical orthogonal function(EOF)analysis reconstruction method and Gaussian filtering method were used for quality control.Compared to the original observation wind field,the high frequency pulsation of original wind field of wind profile radar can be effectively filtered by EOF analysis reconstruction method and Gaussian filtering method.The comparison between two methods showed that the quality control effect of EOF analysis reconstruction method was better than Gaussian filtering method for the instantaneous disturbance of spatial scale.While for the time-scale instantaneous disturbance,the quality control effect of Gaussian filtering method was better than EOF method.
