In view of difficulty in signal processing for warhead velocity measurement in strong vibration environment, an adaptive filtering algorithm was proposed based on EMD for preprocessing after a series of analysis of static explosion signal.Fragment signal was dissociated for intrinsic mode function (IMF), and bandpass filter system was constructed according to the characteristic of fragment target signal.Then, the cross-correlation value of target signal was calculated in two channels to determine corresponding relationship between them.Finally, characteristic point of the target signal was obtained by maximum slope method to calculate instantaneous speed of fragment.Multiple experimental results show that the algorithm has a certain practical value, which could provide an effective signal preprocessing method to obtain fragment velocity test results in strong vibration environment accurately.
