In this article, a single reference Dicke radiometer operating over 1.2 GHz-1.4 GHz for clinical applications was developed and characterized using a temperature controlled test load.Abstract:
This paper presents the development and characterization of a single reference Dicke radiometer operating over 1.2 GHz-1.4 GHz for clinical applications. A variable hot noise source is designed using a peltier module for calibrating the radiometer. System characterization was carried out using a temperature controlled test load to obtain the calibration curve of the device. The accuracy of the calibrated single-reference Dicke radiometer is reported for a matched test load at thermal steady state.read more

Noninvasive measurement of subcutaneous temperature using active antenna and high gain low noise microwave radiometer
TL;DR: In this paper , a radiometric thermometer designed in 1.575 GHz band consists of a near-field probe and a high gain Dick radiometer, and the measured results show that the active probe antenna provides additional 12.5 dB gain with noise figure less than 1dB.

Modeling the Visibility of Breast Malignancy by a Microwave Radiometer
F. Bardati,S. Iudicello +1 more
TL;DR: The radiometric weighting function has been evaluated as a function of the size of a contacting antenna modeled as an aperture antenna and the results show that this difference signal depends on the average over-temperature in the lesion times the heating efficiency.
