Title:
RADIOMETER FOR MICROWAVE RECEIVER AND METHOD FOR MEASURING TEMPERATURE OF PROBE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/225156
Kind Code:
A1
Abstract:
A radiometer for a microwave receiver according to an embodiment of the present invention comprises: an antenna line through which radiation power corresponding to the temperature of a probe is received from an antenna; a first reference rod having a first reference temperature fixed in advance; a second reference rod having a second reference temperature fixed in advance; a first microwave switch for selectively switching the antenna line, the first reference load, and the second reference load; a second microwave switch switched with the same clock as the first microwave switch; a demodulator for multiplying a signal output from the second microwave switch by a predetermined gain value and outputting same; an integrator for integrating the signal output from the demodulator; and a controller for measuring the temperature of the probe on the basis of a signal output from the integrator.
