| Abstract: | In this paper,A plan to extract the weak signals from interference based on MSD wavelet transform algorithms is proposed.Through the weak signals extraction from the simulation noisy models and realistic IR seeker data,it can be seen that MSD wavelet transform algorithm processes high calculation speed,real-time processing ability,and it is able to suppress noise inference and adapt to wartime needs. |
