Abstract The new generation weather radar is an important detection equipment for meteorological departments to conduct short-term approaching forecast of weather process and monitor strong convective weather.The radar echo intensity of the location of the detected meteorological target can reflect the precipitation intensity of the location.In order to ensure the accuracy of the radar echo position,it is necessary to check and calibrate the spatial location of the radar regularly,so as to eliminate the distortion of the radar echo position caused by the spatial positioning error.The CINRAD/CC and CINRAD/CA are two different models of C-band new generation weather radar.Although the principles of the two different radars' spatial positioning are the same,however there are differences in specific operating procedures of spatial positioning and deviation calibration.This paper elaborates the principle of radar space positioning,and introduces the operating procedures of space positioning and error calibration of two C-band new generation weather radars in detail,hoping to provide reference for the technical support personnel of weather radar.
