Abstract
Summary
In this paper, a new slip sweep harmonic elimination method being independent of ground force is proposed. The method is a CEEMD-based (Complementary Ensemble Empirical Mode Decomposition based) method. It gets the Intrinsic Mode Function (IMF) component by performing CEEMD to the correlated trace data of slip sweep and conducts attenuation processing to the IMF components contaminated by harmonic noise to finally reconstruct the correlated harmonic-eliminated trace data so that the effective suppression to slip sweep harmonics is realized without ground force. Actual data application shows that this method has a significant harmonic elimination effect.
