摘　　要：测量雷达定标是影响飞机RCS动态测量精度的关键因素。根据RCS动态测量基本原理,分析了RCS动态测量雷达的定标技术,包括定标体、定标距离、悬挂方式、定标时机等内容,详细讨论了影响定标精度的各种因素。结合实际测量流程对测量雷达的定标不确定度进行了分析,最后对RCS测量不确定度评估结果的准确性进行了验证。The calibration of measuring radar is considered as the key factors that affect the dynamic RCS measurement accuracy of aircraft. Based on the fundamental theory of dynamic RCS measurement, the calibration technology of RCS measurement radar is analyzed, including calibration object, calibration distance, hanging way and calibration timing, etc. The factors that affect the calibration accuracy are discussed and in conjunction with the actual measurement process, the uncertainties of measuring radar calibration are analyzed. Finally, the precision of the evaluation results of the RCS measurement uncertainty is verified.
