The new radiometric method for underlying surface relief form creation with the two-antenna radiometer is offered. The main point of a method is searching the maximum directions of the antenna pattern partial beams when the directions are crossed on the same site of object. Two known directions and base of system allow to calculate coordinates of a site of spatial and extended object. Block diagrams of the systems realizing the offered method of signal processing are developed.
