The work is devoted to the peculiarities of obtaining holograms and reconstructing (restoring) images from them in the radio range of electromagnetic waves. Obtaining and restoring subsurface radio holograms is an urgent task in the field of detection, identification and non-destructive testing of hidden objects. Measurement of radio holograms is usually performed with a step, the value of which takes into account the properties of the object and ignores the phenomenon of diffraction on the object and its elements. Such holograms contain redundant information. The work shows that the volume of measurements when obtaining holograms of comparable quality can be significantly reduced if the choice of step is made taking into account the phenomenon of diffraction. The practical result of the proposed article is the ability to select the scanning step of holograms with the purpose 1) maintaining image quality while reducing the number of hologram measurements; 2) maintaining the number of measurements while increasing the quality of the reconstructed image.
