When testing short-term explosive shock signals with wideband and high-amplitude characteristics

the problem of zero drift due to signal distortion is often encountered.Although empirical mode decomposition(EMD)is commonly used to eliminate zero drift

its inherent mode aliasing defect can lead to unsatisfactory processing of explosive signals.To address this problem

fast ensemble EMD(FEEMD)and complementary ensemble EMD(CEEMD)are introduced to process zero drift signals

and their performance is compared and analyzed with that of the EMD method.The results indicate that compared to EMD and FEEMD

CEEMD has the best zero drift elimination effect on explosive shock signals

which can eliminate trend terms while preserving high-frequency details.This method improves the accuracy of analyzing explosive shock environments.
