阿伦方差 - Allan variance estimated by simulated noise and calculated theoretically using power law model are well matched . the effect of phase noise on azimuth focusing is given by monte carlo experiment
模拟相噪得到的allan方差估计值与幂律模型得到的allan方差理论值符合得较好。 - The allan variance ( av ) analysis method is used to evaluate the hrg signal . the result indicates that the main random error of hrg is angle random walk ( arw )
论文采用allan方差法对半球谐振陀螺的信号进行随机误差分析,分析结果表明,半球谐振陀螺的角度随机游走误差是陀螺随机误差的主要部分。 - In this paper , optic gyro is viewed as the object of investigation and several aspects is investigated as follows . two important indexes - bias instability and scale factor were measured and investigated , including bias , its repetitiveness , temperature sensitivity , random walk coefficient and scale factor , its nonlinearity , asymmetry , repetitiveness . we make use of the allan variance method to separate the noise factors which affect the performance of the optic gyro , such as the angle random walk , bias instability , rate random walk , rate ramp , quantization noise , markov noise and sinusoidal noise
本文以光学陀螺为研究对象，开展了以下几方面的研究工作：本文对光学陀螺性能的两个重要指标?标度因数和零偏稳定性进行了较为详细的研究，其中包括陀螺的零偏b _ 0 、零偏重复性b _ r 、零偏温度灵敏度b _ t 、随机游走系数rwc和标度因数k 、标度因数的非线性k _ n 、标度因数不对称性k _ h 、标度因数重复性k _ r等等。 - Since 1960 " , the methods for charactering time - frequency stability in time - domain have been in progress . the methods include allan variance , modified allan variance , time variance , hardamard variance , total variance , time interval error ( tie ) and maximum time interval error ( mtie ) , of which tie and mt1e are usually used for telecommunication network
