  • To accurately measure the amplitude and duration of exciting pulse for calibration of a high-g accelerometer, the measurement method of the exciting pulse was studied in this paper. Based on the analysis of the principle of Laser Doppler, a grating laser velocimeter was designed. A local mean decomposition algorithm based on polynomial fitting and Hilbert transform was put forward to process the Doppler signal with zero shift. The acceleration pulse was calculated using the above algorithm and the uncertainties of measurement of the amplitude and duration were analyzed and calculated. The expanded uncertainties verified by experiments are 3% for the amplitude and 4.8% for the duration with a coverage factor k =2. This method is effective for pulse measurement and the measurement precision met the requirements of ISO16063-13(2001).
