Study on Usage of Digital Signal Processing Techniques inDe-noising Optical Gyro Output Signal

摘要

In allusion to the effect of optical Gyro outputrnrandom noise, this paper presents a adaptive signalrnprocessing techniques. Compared to the method basingrnon traditional Kalman-filter, the proposed technique isrnsimple for design and implementation in real-timernprocesses, and the proposed technique does not imposernany restrictions on the statistical properties of the randomrnnoise component associated with the optical Gyrornoutput. The test results on northfinding based on RingrnLaser Gyro(RLG) and full-attitude of fiber opticrngyro(FOG) show the proposed technique can improvernthe accuracy greatly.
