Abstract The article uses the S-band dual polarization radar(CINRAD-SAD) in Lianzhou and the X-band dual polarization phased array radar(XPAR) in Fogang,Yingde,Qingcheng,and Qingxin in southern Qingyuan from July 1 to December 31,2022,to compare and analyze the consistency,stability,and reflectivity factor differences of the two radars using spatiotemporal data matching and comparative analysis methods.The results showed that after joint networking,the fitting results of reflectance in the 10-35 dBZ area were relatively ideal,and the fitting effect was the best in the 20-35 dBZ area.As the SAD reflectance increases,the difference between XDPAR reflectance and SAD reflectance also increases,with an overall difference of -1~7 and a median of 1~4.The deviation is small,but there are many singular values in the 5-35 dBZ region.
