| 摘 要： | 本文给出了多项式微分平滑速度输出方差比的精确表达式及截断误差上界的一个较为准确的估计；提出了采用奇次多项式进行非中心输出的微分平滑方法；在同时考虑截断误差与方差比的情况下，得到了最佳滤波，并进行了实算检验。

| Abstract: | In the paper,the exact formula is found for output variance ratio of velocity of differentially moving average with polynomial,and the truncation error bounds are estimated accurately The method of noncentral output for differentially moving average with the polynomial of odd degree is applied when the truncation error and variance ratio are considered simultaneously,the best filter is obtained The results are tested with imitationg compute |
