ROTARY DEVICE FOR MEASURING AMPLITUDE DIAGRAMS OF REVERSE DISSIPATION OF LARGE DIMENSION OBJECTS Russian patent published in 2007 - IPC G01R29/10 

FIELD: radiolocation.

SUBSTANCE: in accordance to the invention, on a round platform, meant for placement of large-dimensional object, supported by air cushion or vertical shaft, mounted in a well of foundation, at its center a metallic area in form of truncated cone, closed on top, is rigidly held at its center. Height of area is determined from formula H_ar0,71(H_ob-H_ch), where H_ob, H_ch - height of object and height of its wheel chassis. Diameter of upper part of area equals diameter of platform, and diameter of lower part - D_{ar l} = D_{ar u} + 2H_arctgα, where D_{ar u} - diameter of upper part of area and α - inclination angle of cone generatrix.

EFFECT: increased precision when measuring reverse dissipation diagrams of large dimension objects near underlying surface in millimeter-decimeter wave length ranges with simultaneous expansion of area of usage of device.
