Abstract:
Interference Fiber Optic Gyroscope (IFOG) is the mainstream Interferometric Fiber Optic Gyroscope (IFOG) is the mainstream optic inertial sensor products of rotation measurement in nowadays. However, short time migration as well as long time bias had been impacting IFOG for the first day it invented. For a better operation of orthogonal demodulation algorithm, which we proposed before had demonstrated an ability of suppressing the noise in IFOG. This article firstly concerning about the initial phase in the orthogonal demodulation of IFOG. Through posteriori estimation we achieved the balance orthogonal demodulation. Secondly, we place the 2 orthogonal channel data obtained from the IFOG, as reference signal for each other into an adaptive filter module, based on the LMS principle, obtaining a real-time improvement of short time migration and long time stability.
