摘要
新一代天气雷达是气象部门进行短时临近预报和监测强对流天气的重要探测设备,其探测到的气象目标物所处位置的雷达回波强度能够反映该位置的降水强度。为了确保雷达探测回波位置的准确性,需要定期对雷达的空间定位进行检查和误差标校,消除因空间定位误差造成雷达回波位置失真的影响。CINRAD/CC和CINRAD/CA是2种不同型号的C波段新一代天气雷达,虽然两者空间定位原理相同,但在空间定位及误差标校的具体操作上却有所不同。文章对雷达空间定位原理进行了阐述,并对2种C波段新一代天气雷达的空间定位及误差标校操作规程进行了详细介绍,希望能为天气雷达技术保障人员提供借鉴。
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.
