Discrete radon transform [PDF]
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1987 This paper describes the discrete Radon transform (DRT) and the exact inversion algorithm for it. Similar to the discrete Fourier transform (DFT), the DRT is defined for periodic vector-sequences and studied as a transform in its own right. Casting the forward transform as a matrix-vector multiplication, the key observation is that the matrix-although ...

A Weak Target Detection Algorithm IAR-STFT Based on Correlated K-distribution Sea Clutter Model [PDF]
Radioengineering, 2023 The detection performance of weak target on sea is affected by the special effects of sea clutter amplitude. Aiming at the time and space correlated of sea clutter, the correlated K-distribution sea clutter model is established by the sphere invariant ...

Mathematical model of non-stationary diffusion – advection of radon in the soil – atmosphere system [PDF]
E3S Web of Conferences, 2023 A one-dimensional mathematical model of non-stationary diffusion - advection of radon in the soil - atmosphere system is considered. Using the integral Laplace transform, an analytical solution of the mathematical model was obtained and, on its basis ...

Bargmann–Radon transform for axially monogenic functions [PDF]
, 2020 In this paper, we study the Bargmann-Radon transform and a class of monogenic functions called axially monogenic functions. First, we compute the explicit formula of the Bargmann-Radon transform for axially monogenic functions, by making use of the Funk ...

Crosstalk attenuation for imaging of multiples based on angle gather residual moveout analysis
Frontiers in Earth Science, 2023 Imaging of multiples, as a supplement to imaging of primaries, can provide a wider range of subsurface illumination. Therefore, it can provide more detailed information on subsurface structures. However, imaging of multiples suffers from crosstalk issues
