| 传统的集成系统校准采用单台仪器计量和系统功能检查来完成，系统性能和技术指标无法保证，雷达射频测试系统的整体校准是目前急需解决的问题。本文通过设计组配标准化、通用化的现场传递标准件，即通过组配单件传递标准件、组合传递标准件，建立与雷达射频测试系统相对应的功率、幅度、相位、噪声和反射系数等电参数的工作标准，通过对以上各参数的不确定度分析和评定、重复性和稳定性的考核，解决雷达射频测试系统的量值传递问题，实现雷达射频测试系统的现场整体校准。 |

| Traditional integrated system calibration is performed with single instrument measurement and system function checks, and the performance and technical specification of the system are not guaranteed. The overall calibration of radar RF test system is an urgent problem at present. Standardized and generalized standard parts for in-situ transfer are designed and assembled, that is, with assemble of sheet transfer standard parts and portfolio transfer standard parts, this paper establishes a working standard for radio parameters as power, amplitude, phase, noise and reflection coefficient and etc. corresponding to the Radar RF test system. By analyzing and evaluating the uncertainty and checking repetition and stability of the above parameters, it resolves value transfer problem for radar RF test system and realizes local integral calibration. |
