| 摘要: |
| 针对机抖激光陀螺角随机游走和发动机干扰等影响静态捷联寻北精度的问题，提出了一种新的基于区间正交小波变换的前向线性预测算法。该算法利用前向线性预测技术以及区间正交小波变换抑制边界效应的能力，有效地减小了角随机游走和发动机干扰。车载实验证明该算法的有效性。 |

| Abstract: |
| The paper deals with the effects of the angle random walk and engine jamming on SINS alignment. An algorithm is proposed which is based on the interval wavelet transform and forward linear prediction. The algorithm uses forward linear prediction and the ability of the interval wavelet transform to restrain terrible edge effects, thus, the angle walk and engine jamming are reduced effectively. The results prove the feasibility of the method. |
