Methods for the space-time processing of ultra-wideband signals used in short-range and ground penetrating radar as well as exploration seismology for execution of migration transformation procedures are analyzed. Procedures for obtaining the geometricalal parameters (position, shape, and orientation) of reflecting boundaries and diffracting objects from signals recorded during scanning in some spatial zone are proposed. Different methods for the implementation of linear and nonlinear migration transformations are analyzed. Frontal migration transformation methods are analyzed in more detail and advantages of these methods are demonstrated. Interactive and computer-aided versions of such methods are presented. Analytical relationships for the implementation of these versions of the space-time signal processing are presented.
