Receiving the Radio-Holographic Images of Objects on the Basis of Disperse MIMO-Type Antenna Arrays with the Single-Frequency and Multi-Frequency Radiations

The radio images of closely set objects are received using the spatially multichannel radar systems based on the transmitting and receiving disperse uncontrollable antenna arrays of MIMO type. With emission of the single- and multi-frequency signals orthogonal in time, the generalized uncertainty function in spatial coordinates is calculated, and examples of focusing the radio images of multi-point objects with high resolution are given. It is declared that the radio image construction in coherent MIMO-type radar systems of small range is equivalent to the new radio-holographic method of multi-static radio holograms.
