DEVICE FOR MEASURING REFLECTANCE OF RADIO WAVES FROM RADIO-ABSORBENT COATINGS Russian patent published in 2016 - IPC G01R29/08 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used for measurement of coefficient of reflection of radio waves from radar-absorbent coatings (RAC) at small angles of radiation. Said result is achieved by the fact that the device for measurement of coefficient of reflection of radio waves from RAC has series-connected receiving antenna, receiving device, computer device, control unit and transmitter with transmitting antenna, as well as rotary support and separating plate of radar absorbent material, which is installed between receiving and transmitting antennae, wherein the receiving device with receiving antenna are mounted on linear displacement in horizontal plane that is connected to the third output of the control unit, besides, control unit second output is connected with rotary support, on which alternatively angle reflector is arranged with the analysed sample RAC and corner reflector without it (reference sample), the ratio of linear horizontal sizes of faces of which is selected in the scale of not less than 1:1.8, besides, the corner reflector is arranged on rotary support so that its rotation axis is line parallel to the edge of the corner reflector and passing through the middle of the sample RAC.

EFFECT: technical result-increase of accuracy of measurements of coefficient of reflection of radio waves from RAC.
