Wavelet Transform and Interference Elimination of Fixed-Point Deformation
Pressure Interference of Kuancheng Station |
| |
| Abstract: | Through wavelet decomposition, the typical events of the fixed-point deformation instruments of Kuancheng station are analyzed by atmospheric pressure interference. We obtain the characteristics of atmospheric pressure interference on different instruments in different frequency bands. We eliminate interference and achieve better results. |
