STUDY OF DATA PROCESSING OF WIND FIELDS FROM DOPPLER RADAR

A “K-Neighborhood Frequency” method for preprocessing the wind fields from Dopplerradar is presented .It is relatively clear in physical significance and can effectively process the “noises” in the wind fields .Based on it, a “Double Radial” method is used to unfold velocity, and a good result is gained .A new person-computer interactive method for obtaining 90 % or higher correction is also designed, which can improve greatly the traditional way of person-computer interaction .
