摘要: |
在航天飞行器测量中,测量噪声是不可观测的。这就需要对含有误差的测量数据进行预处理以获得测量噪声的信息。本文从理论上对广泛应用的两种模型进行了系统性的研究,为处理方法的合理性提供了理论依据,并用仿真结果进行了验证。 |

Abstract: |
Measuring noise in aircraft tracking and measuring can't be observed and hence it must be pre-processed to obtain information about measuring noise. In this paper,we conduct a systematic study of the two models that are applied extensively and present theoretic bases for processing method. |
Keywords: data processing,stationary test,difference method,LS method |
