Abstract

The parametric model method is the main method of modern power spectrum estimation. Power spectrum estimation based on AR model is one of the common methods of parametric model method. In this paper, the application of the Burg method of AR model in laser Doppler tachymetry is studied. The spectrum estimation of the AR model based on the Burg algorithm is used to analyze the laser Doppler signal with a speed range of 10~100m/s. An AR model with relative frequency error within the range of actual engineering requirements is established. The analysis results show that the spectral estimation of the AR model based on the Burg algorithm has high extraction accuracy of Doppler shift.
