激光陀螺量化过程的概率模型与分析

Probability distribution model and its analysis for the quantizing process of laser gyro

提出了激光陀螺量化过程的概率分布模型,在此基础上,分析了量化过程对激光陀螺性能的影响,并给出了量化前后陀螺数据均值和方差之间的关系。仿真实验发现,量化前后陀螺数据的均值符合得较好,但方差却没有简单的对应关系,结论对分析激光陀螺的实际性能有着重要的意义。

The probability distribution model of the quantizing process of laser gyro is proposed, then the influence of quantizing process on the performance of laser gyro is analyzed.The relationship of the mean and the variance between pre-quantizing data and post-quantizing ones is presented. Simulated examples validate that the mean of the pre-quantizing data is according with the post-quantizing ones, but the relationship of the variance between them is complex. All those results will be helpful to analyze the real performance of laser gyro.
