Abstract: A rapid-converging ultrahigh-frequency microwave rainfall data discretization method. The method comprises: discretizing each link in an ultrahigh-frequency microwave network into a plurality of segments of short links; taking the central point of each short link as a virtual station, and determining a central station and a side station in each link; and performing estimation for a virtual station on each link, performing calculation, by means of IDW, by using rainfall intensity estimators of all central stations of other links except the link, correcting a calculation result, and performing successive iteration until an iteration termination condition is met, so as to complete discretization. The method is more scientific and realizes a higher convergence speed. Aiming at the features of an ultrahigh-frequency microwave network, only a central station participates in optimization calculations, so that errors introduced to a model after station discretization are greatly reduced. Accordingly, during a rainfall data processing process, only the central station is used, such that the arithmetic speed is not limited by the number of virtual stations.
