A dual-polarization Doppler Weather radar with narrow beam of C-band was installed at Nanjing University of Information Science & Technology. To verify its observational capability and potential applications, high-resolution radar data were comprehensively analyzed. The radial positioning bias was adjusted based on the echoes of the stationary references. Moreover, the differential reflectivity (ZDR) bias was calibrated by the online solar signals. Also, the radar data retrieved from both convective and stratiform precipitation were performed. The results showed that the resonance scattering effect, various precipitation particle information, and non-uniform beam filling (NUBF or NBF) existed. Besides, tilt precipitation structure and possible supercooled water evidences were revealed.
