摘要
给出了激光陀螺噪音分析方法及噪音模型,据此模型比较研究了四种激光陀螺在不同解调方案下噪音组成分量之间的关系;理论分析了激光陀螺噪音分量的特性和引起该噪音分量的因素,给出了典型的试验数据和曲线.研究结果表明,该模型不但可以用于对激光陀螺的随机游走系数的估计.而且,该模型的其他系数可以用于研究陀螺的量化和解调误差,也能用于评估陀螺输出的速率噪音.
The method for analysis of laser gyro output noise and the model of the noise are given. Using the model,the output noises of four types of laser gyro are analyzed by different de-modulating ways in theory and experiments. The noise term and its causes are researched theoretically. The experiment data and noise curve are given. The results show that the model can be used for evaluating the random walks coefficient, the quantization error,de-modulating errors,and the output rate noise of the laser gyro.
