Paper Abstract

Image resolution for RF/microwave relatively long waves is limited by the diffraction limit (Abbe diffraction limit). Each point of reflecting object will work as source of diffractive waves if wavelength longer than object. But phase front of diffracted waves still will consist information about object shape. Image can be recovered from multi frequency digital hologram by combination of interferograms. In this case resolution of recovered image will be determined by receiver bandwidth, digitizing frequency and accuracy of processor time. Faster processor - better image resolution. Low frequency non-scanning wide beam in monopulse radar system can cover all object and same time provide high resolution phase measurement relative to reference beam.
