Abstract
As an important strategic weapon, submarine detection is very difficult. Aeromagnetic detection is one of the main detection methods, but there are some problems such as complex measurement environment and difficult recognition of target magnetic signals. To solve this problem, wavelet threshold denoising is used to suppress magnetic noise, and WVD is used to analyze the magnetic signal in time and frequency to improve the recognition ability of the unexploding target magnetic signal. The simulation results show that this method is feasible.
