摘要
针对外弹道测量数据中斑点型野值直接剔除困难的问题,从工程实践角度出发,提出了一种基于一阶差分和外推拟合的联合野值剔除方法,即首先对原始测量数据作一阶差分处理,然后再对差分结果数据利用外推拟合法进行野值剔除。实验结果表明,该方法能有效剔除外弹道测量数据中的斑点型野值,保证了数据处理结果的正确性。
Aiming at solving the difficulty of the direct elimination spotted outliers of ballistic measurement data, from the point of view of engineering practice, a new method is proposed based on the first-order differential and extrapolation fitting, that first raw measurement data is manipulated by first-order differential method, then the outliers of the differential result data are eliminated by the extrapolation fitting method. The experimental results show that the spotted outliers of exterior ballistic measurement data can be effectively elim- inated by using the method proposed which ensures the correctness of the results of data processing.
