| 摘要: |
| 建立了多部雷达情况下的系统误差观测模型, 分析了系统的可观测度, 得出可观测度不一定随观测数据的增多而增强的结论。在此基础上, 通过数据筛选的方法, 可以获得一个使系统可观测度增大的观测子集, 用于误差估计。实验结果表明, 使用本文的方法, 可确保估计算法的有效性。 |

| Abstract: |
| In this paper, a systematic error observation model for multiple radars is established, on the basis of which the system observability is analyzed and a conclusion is drawn that measurement accumulation does not always lead to higher observability. According to the conclusion a measurement subset can be produced by means of data selection, which causes higher system observability, to estimate the systematic error . Simulation result shows that the method proposed in this paper can ensure the validity of estimation algorithm. |
