    Hydrogen gas detection technique is very important because it is very flammable and explosive. A Raman lidar system is one of the
    techniques for the detection of hydrogen gas remotely. The signal to noise ratio of the Raman lidar is not high, because Raman
    scattering signals by the hydrogen gas are very weak and its signals include the background noise signals such as the pumping laser,
    laser-induced fluorescents signals, and ambient light. This paper discusses the improvement of the accuracy of the Raman lidar system
    for measuring hydrogen gas by eliminating the background noise signals. To verify the accuracy improvement effects, experiments
    of measuring the hydrogen gas concentration are carried out. As the results of the experiment, The coefficient of the determination(R2)
    of the calibrated Raman signal of the hydrogen gas distribution by using the background noise signals was improved from 0.9985
    to 0.9995 and the mean of the measuring error rates are decreased from 0.9794 to 0.7179, which is an improvement of about 27%.
