| Abstract: |
| The measured data by space tracking ship contain complicated ship deformation an
d ship-swaying
period,which cases the difficulty to process the abnormal values.According to th
e data characteristics of ship, a
specific study is performed on the selection results of several identification m
ethods.With moving median smoothing
estimation model, an adaptive processing method for measured data is designed. D
ynamic adjustment between smoothing
intervals is implemented by applying periodogram analysis, thus accomplishing th
e error correction of measured data
by tracking ship. |
