External Calibration experiments of airborne millimeter-wave Cloud Radar Using Corner reflectors

On April 2016 19-24, a calibration experiment based on corner reflector was carried out in field test zipengshan in Feixi County of Hefei city. The experiment had accomplished the calibration of airborne millimeterwave cloud radar under the condition of static ground. According to calibration data, the root mean square error of corner reflector strength measurement values between the reflector and the theoretical value is 0.182dB and 0.197dB in standard mode (pulse width is 0.33 s) and enhanced mode (pulse width is 1.32 s) respectively. All these pave the way for the further study of the external calibration experiments under the condition of clear sky sea.
