WebWe mainly emphasize the role of Radon transform as a signal identiﬁcation and enhancement tool, a view often shared in exploration seismic applications. It should be recognized, however, that Radon transforms can be generalized to solve the linear Born scattering problem with asymptotic Green functions. WebJun 5, 2013 · In this study, a new method based on Radon Fourier transform (RFT) and keystone transform (KT) for high-speed maneuvering target detection is proposed. The proposed algorithm utilizes second-order KT to correct the range curvature, and the improved dechirping method to compensate for the Doppler spread.

WebWe study the symplectic Radon transform from the point of view of the metaplectic representation of the symplectic group and its action on the Lagrangian Grassmannian. … WebOct 24, 2009 · There are two main ways of generalizing the Radon transform. One can add a weight to the hyperplane integral or one can integrate over subvarieties that are not linear. The first idea leads to the generalized Radon transform in ℝ n that we study in section 5.4.
