RADIOTHERMOMETER Russian patent published in 2021 - IPC G01R29/08 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment, namely, to apparatuses for measuring the characteristics of an electromagnetic field, applied in non-destructive testing of dielectrics, medicine. The technical result is achieved due to the fact that the radiometer comprises an antenna and a temperature-controlled circuit board whereon a matched load and a noise generator are placed, and therein differs from the prototype in that the output of the antenna is connected with the first input of the first switch, the output whereof is connected with the first input of the directional coupler and the second and third inputs are connected with the output of the short-circuiting switch and the third output of the control unit, respectively.

EFFECT: increase in the accuracy of measurements and structural simplification.
