... is used to merge the three functions into one that defines the same operator in the slant-stack domain. Each input sample is smeared as a sinc function onto the output panel in the slant-stack domain, along the DMO operator trajectory. Then, an accurate and efficient inverse 3-D slant-stack transform...

... the initial signal model is accomplished via a weighted slant stack (WSS) method. The original WSS method was designed for 3D poststack applications (Martinez et al., 2000), and later extended for prestack data. The 3D WSS is achieved by combining two 3D slant stacks. One slant stack transforms the data after...

.... The idea of such a decomposition is not new (Ottolini, 1983a) and has been accomplished previ- ously with the help of a local slant-stack (or windowed Radon) transforms (Ventosa et al., 2012). However, the fundamental slope-distance uncertainty makes it difficult to control the res- olution of local slant...
