METHOD OF OBTAINING RADIO HOLOGRAMS OF SUBSURFACE OBJECTS Russian patent published in 2013 - IPC G01V3/12 

FIELD: radio engineering, communication.

SUBSTANCE: method involves step-by-step measurement of a signal in a given frequency range with uniform spacing to where: k_min=0.72; k_max=0.81; D is the antenna diameter; c is the speed of light; the number of separate frequencies in the range from f_min to f_max is not less than five; the method being characterised by that it involves further automatic equalisation of the amplitude-frequency characteristic by changing the transmitter power; equalisation of the amplitude-frequency characteristic can also be carried out by changing receiver gain.

EFFECT: higher depth of detection of objects in condensed media.
