| 摘要: |
| 本文研究再入弹道参数的自适应估计。所采用的方法对动力学模型噪声的未知统计特性进行补偿，并对状态参数与测量设备的系统误差交叉进行估计。仿真结果表明，无论是状态参数的估计还是测量系统误差的估计，都具有较高的精度。 |

| Abstract: |
| In this paper,an adaptive estimator of reentry trajectory parameters is proposed. The method can compensate for the unknown statistic characteristics of the dynamic noise. And it can give adaptive estimation of both state parameters of the trajectory and systematic errors of the measuring equipments in an interactive way. The simulation result indicates that the adaptive estimator has high precision. |
