Abstract:

In order to solve the problem of precipitation particle classification in the case of random missing of polarization parameter data of two-polarization meteorological radar, a method based on matrix completion(MC) and decision tree support vector machine multi-classifier(DTSVMs) is proposed. First, the polarization parameter data with random miss is reconstructed according to the matrix completion algorithm, and then the training data are used to learn the DTSVMs, and finally the precipitation particle classification of the reconstructed data is realized by using the DTSVMs with good learning. By processing the measured data and analyzing the results, it is proven that this method can effectively solve the precipitation particle classification problem in the case of random missing of polarization parameter data.

Key words: dual polarization weather radar, hydrometeor classification, matrix completion, support vector machine, random missing
