RADIOMETRE TO ANALYSE OBJECTS ADJOINING ANTENNA Russian patent published in 2011 - IPC G01R29/08 

FIELD: physics.

SUBSTANCE: proposed radiometre comprises receiver, antenna, modulator and first directed coupler, current source and noise generator. Besides, it additionally incorporates second directed coupled connected in between output of first coupler and input of receiver input, and switch with its input connected to noise generator output, while first and second outputs are connected with second inputs of first and second directed couplers. To receiver output connected are synchronous low-frequency filter, high-frequency filter, comparator, control unit with its first, second and third outputs connected to relevant control inputs of synchronous low-frequency filter, switch and modulator, while its fourth output makes radiometer output bus. Comparator second input is connected to radiometer common bus.

EFFECT: simplified design and signal processing algorithm.
