基于B样条的外弹道测量数据野值处理方法
Outliers processing method of ballistic measurement data based on B-spline
【摘要】 针对常规野值剔除方法依赖门限容易造成漏检和误判的现象,根据外弹道测量数据的特点,提出了基于B样条外弹道测量数据野值剔除与重构的方法。介绍了该方法原理及实现的具体算法,并采用"多项式+正态测量误差"模型的仿真数据对该方法进行了验证。结果表明,利用该方法既剔除了测量数据中的野值,又保证了数据的原始形态。
【Abstract】 According to the characteristic of ballistic measurement data.A method of outliter elimination is proposed in this paper to overcome the shortage of relying on threshold of conventional method.The paper introduces the method’s principle and arithmetic,and validates the method by adopting t hemodel of "polynomial+ normal measure error ".The result of emulational analysis shows that the method eliminated outliter data.And then preserves original appearance of the data.
