摘要

Output data swatch of fiber optic gyro (FOG), which is not a smooth and random course, are taken the statistical test and smooth disposal with: establish 3 different ARMA mathematical models from the disposed swatch; based on ARMA models, system equations and observations are set up, then Kalman filter is carried out. The results of simulation shows that: Kalman filter, which bases on AR (3) model, can effectively eliminate random noise and compensate the FOG' random error.
