| 摘 要： | 为了克服舰船导航中Kalman滤波器因野值引起的发散，从“新息”入手，利用“新息’’判断野值，通过指数加权的方法找到野值点的新“新息”代替原来的“新息”，达到剔除野值的目的，在舰船组合导航仿真中证明了这种方法是有效的。

| Abstract: | The purpose of this paper is to eliminate the divergence of the Kalman filter caused by the outlier. The outlier is judged by using innovation, and the original innovation is replaced by new one which is given with method of exponential weighting. The results show that method is effective in ship's integrated navigation. |
