Detecting signals of a hemispherical resonator gyro (HRG) with multiple electrodes

The signal detecting method of a hemispherical resonator gyro(HRG) was investigated in order to find ways to reduce the influence of non-ideal factors of a gyro's structure on signal detection.After analyzing non-ideal factors of gyro structure,a signal detecting method based on multiple electrodes was developed according to the structure of the resonator and the symmetry of its vibratory modal shape.First,principles underlying signal detection based on multiple electrodes were developed.Then the formulas for processing signals from multiple electrodes were explained in detail.It is then proven that this method effectively improves the accuracy of signal detection and maintains the signal of the gyro through all operations.
