摘　　要：在外场雷达目标RCS测量过程中,通常采用测量已知反射截面积的标准体(如标校球)作为标校基准,从而对雷达系统进行标校。标校球的标校精度对于雷达测量目标RCS值的准确性,有着十分重要的影响。文中在介绍外场RCS测量雷达采用的标校球定标方法的基础上,详细分析了标校过程中的几种主要误差来源及其影响,并有针对性的提出了提高标校精度的方法,有效提高外场RCS测量雷达标校精度。In the outside radar target＇RCS measurement, the marking benchmark usually adopted the measurement of the proved refect sections＇as standard, such as reference sphere, to calibmite the radar system. The reference sphere＇ accuracy calibration have an important impact on the accuracy of radar measure target＇RCS values. This paper, aiming at the calibration method of the reference sphere, which is used in the outside radar target＇RCS measurement, analyzes the centralized error source and its impact in calibration process in detail and provides the method for improving the accuracy calibration, which can Effectively improve the accuracy of radar calibration.
