| 摘 要： | 为了提高机载遥感平台在应对气流抖动和外界强干扰时的定位性能,在加速度自适应截断正态分布的基础上,通过Lagrange乘子法将速度方向信息约束到强跟踪滤波中,得到了基于方向信息约束的强跟踪定位算法。仿真表明:该算法通过在线控制使输出残差强制近似正交,充分利用了方向约束信息。与一般的强跟踪算法相比较,在提高定位精度的同时可及时响应空中机动,较好地解决了机载遥感平台在强机动干扰条件下的跟踪定位问题。 |

| Abstract: | As to remote sensing(RS) platform,the performance of its positioning affected by atmosphere dithering and external jamming is improved through using strong tracking positioning algorithm constrained with direction information.Based on adaptive truncated normal distribution of acceleration,the novel algorithm combines conventional strong tracking filter with velocity-direction information by Lagrange multipliers.Simulations show that compared with STF,the proposed algorithm may quickly respond to maneuvering... |
| Keywords: | positioning remote sensing platform direction information constrain strong tracking filter adaptive truncated normal distribution |
