Method and system for identifying difference between adjacent body scanning data of weather radar

The invention relates to a method and system for identifying difference between adjacent body scanning data of a weather radar. The method comprises the following steps that an elevation angle layer and corresponding radial data in the body scanning data of the weather radar are obtained; abnormal points in the radial data are identified according to a verification formula; the probability distribution in each elevation angle layer is counted according to the abnormal points; and whether body scanning data of the weather radar is trustable data is determined according to the probability distribution of each elevation angle layer and a preset threshold. According to technical schemes of the invention, the significance of difference between more than two pieces of radial data can be examinedsimultaneously on the basis of an F verification formula in statistics and analysis on the sum of squares, and abnormal change of discontinuous echoes caused by abrupt data change of the radar data can be detected. 本发明涉及一种识别
