高g值加速度计激光干涉校准及信号解算方法
Calibration of the High-g Accelerometer with Laser Interferometer And the Method for Signal Processing
摘要
Abstract
The high-g accelerometer is calibrated with the Hopkinson bar to generate the input accelerome-ter pulse and the laser interferometer used for the measurement of that exciting acceleration. The zero-cross method and the phase method are presented for the processing of the Doppler signal. The simulating result shows that the phase method is superior to the zero-cross method with the error of 0. 20%, under the SNR of 30dB. A 988-type accelerometer is calibrated with the input acceleration ranging from 18371g_n to 86806g_n, which has justified the efficiency of the calibration apparatus and the method for signal processing.关键词
