摘要
针对观测数据中的野值影响目标估计精度的问题,分析了它的影响因素,提出了一种基于残差控制的滤波方法,来判断野值属性。仿真分析表明该方法能较好地剔除野值,且不丢失原有测量数据,保证了目标估计的精度。
The outliers in the measured data will have a bad effect on the precision of target prediction. So we ayalyze the affect of the problem. We present a way according to the residual bias to judge the properties of the outhers. Finally the simulation is given, the result indicates that it can eliminate outliers well, and do not miss the measure data. So it can is ensure the precisionσthe target well.
