发明名称 DITHER SIGNAL REMOVER FOR DITHERED RING LASER GYRO
摘要 In a dithered ring laser gyro, a dither reference signal is provided to supp ly information representative of the dither angle or dither angular rate. This information is processed by a signal processor to generate a correction signal which is the sum of (i) a first function of the dither reference signal indicative of the dither angle multiplied by a first coefficient, and (ii) a second function of the dither reference signal indicative of the dither angular rat e multiplied by a second coefficient. The aforementioned co-efficient may be either selected or generated based on historical data derived from the dither reference signal and the usual sensor output signal. In turn, the correction signal is subtracted from the usual ring laser gyro output signal to provide a corrected sensor output signal.
