Non-invasive microwave radiometry thermometry
Physiological Measurement, 1998Near-field microwave radiometry and radiometric imaging are non-invasive techniques that are able to provide temperature information at a depth of up to several centimetres in subcutaneous tissues. They are based on the measurement of microwave electromagnetic thermal noise. This paper describes the basic principles, measurement methods and limitations

Microwave radiometry in biomedicine: A reappraisal
Bioelectromagnetics, 1992AbstractNearly 20 years ago the first papers appeared on biomedical applications of microwave radiometry, and many other papers have since appeared. Yet, despite its unique capabilities, microwave radiometry has so far received only limited acceptance by the medical community, and little commercial success.

Temperature Measurement by Microwave Radiometry: Application to Microwave Sintering
IEEE Transactions on Instrumentation and Measurement, 2009Temperature is a key parameter in industrial manufacturing, and its control is very often directly related to the quality of the products. Microwave-assisted processing has gained worldwide acceptance in powder technologies, in particular for the sintering of ceramic parts.

Microwave radiometry of forests
Waves in Random Media, 2004Abstract Microwave remote sensing observations provide all weather, day/night monitoring of the earth's surface and make it possible to probe forest vegetation at various depths by operating at different frequencies. Significant progress in microwave radiometry of land surfaces has been made by using advanced airborne and spaceborne instruments and by ...

Advances in microwave digital radiometry
IGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2002The increasing availability of discrete and integrated high-speed digital logic has enabled the advancement of microwave digital radiometry for Earth science applications. The first digital radiometers were used for autocorrelation spectroscopy with bandwidths of a few megahertz.

Journal of Navigation, 1966
Before considering in detail the instrumentation involved, it is necessary to establish first of all what is meant by microwave radiometry and mention briefly its possible applications. A radiometer is a device for measuring heat radiation and the title ‘Microwave Radiometry’ is a little surprising in that it implies heat radiation at microwave ...

Microwave Radiometry and Thermography
1989Based on the measurement of the electromagnetic thermal noise generated by living tissues, microwave radiometry is a starting point for a non invasive thermometric process in a depth of the subcutaneous tissues of up to several centimeters.

New Technique for Microwave Radiometry
IEEE Transactions on Microwave Theory and Techniques, 1963An interference modulation technique for microwave radiometry is described. Use of the technique is considered for the development of a radiometer for tuning over a wide range of frequencies, a radiometric device for determining the absolute sensitivity of detectors over a wide range of frequencies, and a means for determining the power level of ...

Advances in Space Research, 1989
Abstract Microwave radiometry provides a useful tool to monitor the properties of snow cover on a global scale. The current state of knowledge of microwave response to dry and wet snow is discussed, and the effects of various snow, soil, and atmospheric parameters to the observed antenna temperature are reviewed.

Microwave Thermal Imaging by Radiometry
17th European Microwave Conference, 1987, 1987Microwave radiometry appears to be well suited for treating thermological investigations devoted to moderately deep seated tissues. These investigations are used in diagnosis and follow up methods (for example in the detection of thermogen tissues, or inflammations such as those consecutive to acute ionization radiations...) and also for the monitoring
