The Research of Detective Procession of AE Signal Under High Background Noise Based on Neural Network

摘要

This paper present a method to detect AE signal under high backgroudn noise based on artificial Neural Network (ANN). In this method, adaptive filtering technology is applied in AE detecting system in the conditions when SNR is poor, so that the parameters of AE signal are more accurate. Computer simulated BP net is used in this paper to train the dates after A/D conversion in AE detecting system. After training, suse the BP net to cut off noise in signal. The primary computer simulating experiments prove that this method is prectisible.
