摘要
以最小渐进方差准则为基础,分析了SαS分布模型参数对Myriad滤波器线性度参数的影响,推导了SαS分布模型参数α与Myriad滤波器的线性度参数K之间的关系曲线,提出了一种线性度参数K的计算表达式,并与传统的经验公式和实际数据进行了比较。结果表明:相对于传统计算方法而言,所提出的公式对实际数据的逼近效果更好、形式更为简洁,具有较强的实用性。
With the asymptotic variance as the criterion, this paper analyzes the influence of the pa- rameter of SaS distribution on the linearity parameter of Myriad filter and derives the optimal a^K curve. A new expression for the optimal linearity parameter K is proposed and compared with the con- ventional emprirical equation and actual data. The results show that as far as the traditional calcula- tion method is concerned, the formula presented is better for actual data fitting due to its simpler form and greater practicability.
