In order to analyze the influence of gyro random drift on opto-electronic stabilization platform accuracy,the Allan variance and power spectrum judgment standards were put forward,in which the time series analysis method was used to establish the model.The FLP filter and wavelet filter were compared based on the applications of stabilization platform,digital low-pass filter,Kalman filter.The experiment proves that the FLP filter is superior to the low-pass filter in filtering the noise at medium and high frequency bands,and is superior to the Kalman filter in keeping useful signal at low frequency bands and finding out the noise characteristics.The results show that FLP filter is suitable for real-time on-line applications of high bandwidth opto-electronic stabilization platform.
