摘要:In view of the wide and effective application of wavelet transform in the study of weak signal detection, it has been applied to the enhancement of magnetic anomaly signal of underwater target. But there is a problem of the decomposition level selection in the process of wavelet enhancement, which is related to the parameters of Aeronautical platform and underwater target. In this paper, based on the detection model of underwater target magnetic field, the selection model of wavelet decomposition level of aeromagnetic anomaly signal was established, and was realized adaptive wavelet enhancement of aeromagnetic anomaly signal by weighted reconstruction. The processing results of the simulation test signal show that the method can effectively enhance the weak magnetic signal of underwater target.
