Fiber Optic Gyroscope Parameter Analysis: Rate Ramp Coefficient, Rate Random Walk, and Bias Stability

This MATLAB program provides comprehensive calculation of various fiber optic gyroscope (FOG) performance parameters, including rate ramp coefficient, rate random walk coefficient, bias stability, angle random walk coefficient, and quantization noise coefficient. The implementation utilizes Allan variance analysis and time-domain statistical methods to accurately characterize gyroscope performance. The program features advanced signal processing algorithms that automatically extract key parameters from raw FOG data through sophisticated filtering and regression techniques. Additionally, the program computes extended gyroscope parameters such as rotational angular velocities along three coordinate axes and the total rotation angle measured over specific time intervals. The code includes modular functions for data preprocessing, parameter estimation, and result visualization, employing numerical integration methods for angle calculation and coordinate transformation algorithms for multi-axis analysis. This tool enables researchers to precisely evaluate FOG performance characteristics, facilitating better understanding of its applications in navigation systems and precision measurement scenarios through robust statistical analysis and performance benchmarking capabilities.
