Popis:	The development of compact indirect microwave holographic set-up by the implementation of low cost, specifically designed directive antennae as transmitter and receiver is proposed. Microwave holograms are recorded by 2D scanning over a plane using motorized translation stage. The recorded interference pattern i.e. holograms are then processed numerically to reconstruct the amplitude and phase information employing the angular spectrum diffraction method. The quality of the reconstructed amplitude image is further enhanced through the deep neural network, in order to combat with the low resolution of reconstructed images. The qualitative experimental results exploit the possibility of developing the miniaturized, and low cost indirect microwave holographic system for near field applications.
