Time Sequence Difference Application in System Error Processing
Problems with systematic errors constitute one of the entangling topics long standing in measurement data. For systematic errors slowly changing with time, time sequence difference is put forward in this paper to eliminate the common systematic errors in measurement data, and then solve the model with least square estimation. Numerical experiment solved respectively by least square estimation and time sequence difference is given at last, the results show that the proposed method can weak the systematic errors effect to the measurement data and get more precise parameter estimation.
