In order to realized the rapid and accurate calibrating of the standard scattering plate uesd in calibrating visibility meter, calibrateing the simulated atmospheric visibility by measuring the scattering coefficient of multiple scattering angle of the standard scattering plate, and the calibration system was calibrated. According to the composition and working principle of the calibration system, the calibration method was determined, the calibration chain of the calibration system was established, and the calibration method for each step of the the calibration chain was designed. By calibrating the standard scattering plate with a given scattering coefficient, the veracity of the calibration result of the calibration system and the correctness of the calibration method were verified. The experimental results prove that the error of the calibration results of scattering coefficient of standard scattering plate is 7.93%, the error of the simulating visibility of the standard scatting plate calibrated by the calibration system is 8.61%, satisfied the requirements of the standard scattering plate used in calibrating visibility meter.
