Simple Calibration of FMCIW 35 GHz Meteorological Radar "PCDR 35"

During first experiments with weather radar PCDR 35 a question of calibration arose. Comparing pixel measurement with the measurement of the same pixel by operational radar we estimated the radar constant to be C 3 = 2. 62∙10 ⁸ , which is tuned to the target distance in [km] and to received power in [mW]. Also all main necessary equations from radar meteorology were cleared in this study and the installation of equivalent radar reflectivity factor was explained based on historical development base. The example of radar reflectivity factor measurement in actual rain event is demonstrated.
