Design and Implementation of Multiband Noncontact Temperature-Measuring Microwave Radiometer [PDF]
Micromachines, 2021 In this paper, a multiband noncontact temperature-measuring microwave radiometer system is developed. The system can passively receive the microwave signal of the core temperature field of the human body without removing the clothes of the measured ...

Microwave Radiometer Instability Due to Infrequent Calibration. [PDF]
IEEE J Sel Top Appl Earth Obs Remote Sens, 2020 We directly quantify the effect of infrequent calibration on the stability of microwave radiometer temperature measurements (where a power measurement for the unknown source is acquired at a fixed time, but calibration data are acquired at variable earlier times) with robust and nonrobust implementations of a new metric.

One-Point Microwave Radiometer Calibration [PDF]
IEEE Geoscience and Remote Sensing Letters, 2020 A method for internally calibrating microwave total power radiometers by using only one level of noise injection is presented. It is based on having a previous accurate characterization of the receiver noise temperature, which used de facto as a second calibration standard.
