Through the extensive investigation of Radon transform with its various improvement and application effects,current research results on Radon transform are summarized. On the basis of introducing the basic principles and applicability of various improved Radon transform methods in detail,this paper focuses on the introduction of using sparse regularization constraints in Radon transform to improve the resolution, and of deriving solution in the restricted model space to improve the iteration efficiency for massive seismic data.Moreover, this paper demonstrates that, the application of Radon transform in seismic vector field pro-cessing is still in the experimental stagehand that its development trend is to obtain satisfactory processing effects as well as to keep the vector characteristics.Moreover,there is an urgent need to design and improve Radon transform methods for multi-component seismic data processing in the immediate future.
