Abstract

Wave data acquisition and processing techniques are suggested to increase resolution of electromagnetic holographic imaging. The techniques take into account priory data about geometric symmetry and localization of an object imaged. It is shown the holographic reconstruction root-mean-square can be improved by using of axial, translational, central and other kinds of the symmetry for current electromagnetic wave situation. An approach to aperture mathematical synthesis is suggested and analysed based on priory information about spatial localization of objects imaged. An interpretation of the approach is presented from physical point of view; its ultimate capabilities are evaluated.
