It may be proved that it is just theAllan variancerelations as fa = 0 and fb = fh.可以证明,当f_a=0、f_b=f_h时,它就是Allan方差公式。
It provides a lot of accurate formulae for spectral density transforming intoAllan variance.本文推导了有限频域;中的噪声引起的修正的Allan方差公式,为噪声的谱密度变换成Allan方差提供了准确的公式。
L 1 RLG was analysed withAllan variance, and the errors which exist in L 1 RLG were given.该文用Alan方差对L－1环形激光陀螺仪进行了具体的分析，得到了存在于L－1环形激光陀螺仪中的各误差源。
Allan varianceestimated by simulated noise and calculated theoretically using power law model are well matched.采用白噪声通过FIR滤波器的方法近似地模拟了闪烁噪声。 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。
