Abstract：This paper uses the standard deviation analysis method to evaluate the quality of radar data from X-band dual-polarization radar with large antenna in northern Jiangsu province.It finds that the reflectivity factor and differential reflectivity data from two X-band dual-polarization radars are comparatively reliable in Dafeng and Baoying.The number of interrelationship is more sensitive to attenuation and interference clutter,etc.,and the data fluctuates widely.In the process of hail weather observation,the standard deviation data of differential propagation phase fluctuates more than the observation data of other types of precipitation processes due to the large influence of hail on the scattering phase difference.Comparative observations of different bands of weather radar found that X-band weather radar played an encrypted coverage of low-altitude weather system observation,but the attenuation phenomenon is still obvious,the maximum echo intensity is about 10dBZ lower than that of S-band weather radar,and the attenuated storm monolith structure has some deformation.
