APPARATUS FOR MEASURING SCATTERING CROSS-SECTION OF LARGE-SIZE OBJECTS Russian patent published in 2013 - IPC G01S7/40 

FIELD: physics.

SUBSTANCE: apparatus for measuring scattering cross-section (SCS) of large-size objects, having series-connected pulsed transmitter, antenna switch, antenna, receiver and computer, the second input of which is connected to a control panel, the second input/output of which is connected to the main rotary support on which the measured object is placed, the third input/output of the control panel is connected to an additional rotary support at whose centre there is a SCS metre, which is in form of a triangular angle reflector, wherein the additional rotary support is mounted on a linear displacement device which is connected to the fourth input/output of the control panel, wherein the additional rotary support is placed between the main rotary support and the transmitter in the same pulsed volume with the measured object.

EFFECT: high accuracy of measuring SCS of large-size objects in the decimetre and metre wavelength range.
