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. |
