Research of Retrieving Doppler radar wind field based on VAP method

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.
