Zusammenfassung:The invention provides a precipitation profile detection radar hydrogel classification method based on fuzzy logic, and the method comprises the steps: obtaining the basic parameters, including effective reflectivity and skewness, of hydrogel classification based on the original signals of Doppler spectrum and echo intensity received by a precipitation profile detection radar; determining the membership degree of the hydrogel according to the effective reflectivity, the skewness and the height, and obtaining the membership strength of all the identification parameters to a certain hydrogel; based on the membership intensity of all the identification parameters to a certain hydrogel, the cumulative probability of each hydrogel is obtained through a fuzzy logic algorithm; and performing defuzzification according to the cumulative probability of each type of hydrogel to obtain recognition results of the hydrogel at different heights. According to the method, the type of the hydrogel can be distinguished from the
