Analysis on metrology specifications for microwave landing system simulator

The authors start with the comprehensive demonstration of performance specifications of MLS stimulator to establish the parameter system for stimulator verification/calibration. Then, based on the principle of angle guidance, they convert the parameters of guidance angel signal to general pulse parameters and reach the value of respective parameters, which can make angle guidance signals measured by normal measurement equipments and traced back to the national standards by uninterruptible traceability chains. They lastly bring forth with the methology of verification/calibration accordingly. The analysis conclusion has dissolved technical obstacles for MLS simulator support and made the MLS specifications accurate and consistent.
