Depend on the working principles of wind profiling radar and application practice, the sounding altitude, spatial and temporal resolution, and measurement errors of the tropospheric wind profiling radar are calculated, and the data availability is analyzed．The results show: through selecting suitable operating waveforms and modes, the radar detection altitude can range from 150 to 12000 meters, and height resolution can be up to 75 m, temporal resolution to 10 minute, wind speed accuracy to 1 m/s, wind direction to 10°, and data availability to over 80%. The conclusions can be used as references for the regional networking of wind profiling radar.
