摘要
我们对环形激光陀螺输出信号进行了时频分析 ,采用Allan方差法对陀螺信号进行了分析与计算 ,应用混合滤波技术对陀螺信号进行了处理 ,并对滤波前后的陀螺测试数据进行了对比分析。Allan方差法分析结果表明 ,该滤波技术能有效提高激光陀螺的精度。
The signal of ring laser gyro (RLG) is analysed in time domain and frequency domain. Allan variance is used in the RLG signal analysis and calculation. Gyro signal is filtered by hybrid digital filter, and the gyro data before and after filtering are analysed by Allan variance. The result indicates that this method can effectively improve the accuracy of RLG.
