Abstract：The deconvolution beamforming method has been applied in beamforming systems in recent years.However,the Richardson Lucy algorithm still faces the problem of noise amplification as the number of iterations increases when effectively calculating deconvolution problems.This article proposes a total variation regularization R-L method by combining Richardson Lucy algorithm with total variation regularization.The new method solves the Richardson Lucy model with total variation regularization term and tests it using simulation data and experiments,achieving good sharpening effect and improving noise suppression ability.
