| 摘要: |
| 建立天基红外低轨星座对自由段目标的观测模型，引入精确的目标运动模型。考虑到算法的数值稳定性，引入平方根UKF算法。理论分析与实验结果表明，平方根UKF算法能够对天基红外低轨星座中自由段目标进行有效跟踪。 |

| Abstract: |
| The measurement model of tracking a ballistic target of coast phase in the LEO space-based infrared constellation was constructed. A suitable accurate target motion model was developed. Considering the robustness of the nonlinear filter, a square root version of the UKF was included. It was corroborated in the theoretical analysis. The simulation shows that the square root UKF (SRUKF) has good performance when tracking a ballistic target in the LEO space-based infrared constellation. |
