METHOD OF FORMING RADIO HOLOGRAM OF OBJECT AND DEVICE THEREFOR Russian patent published in 2015 - IPC G01S13/89 

FIELD: radio engineering, communication.

SUBSTANCE: group of inventions relates to radio imaging and can be used in designing radio systems. The result is achieved by offsetting the frequencies of an electromagnetic wave W₁ which irradiates an object and an electromagnetic wave W₂ which irradiates a spatial plane or a certain curved surface by a value Δf; forming a radio hologram of the object in the form of amplitude-phase distribution of a beat signal with differential frequency Δf of the amplitude of the sum of an electromagnetic wave W₃ reflected from the object and the electromagnetic wave W₂ on the recording region of the radio hologram, which is fixed relative to a signal with frequency f₀=Δf. At the output of a separate channel for recording the radio hologram there is no flicker noise and the constant component resulting from the power of the electromagnetic wave W₂, which improves sensitivity of the detection array without increasing its cost.

EFFECT: low noise level at the output of a separate channel for forming a radio hologram without increasing the cost thereof.
