Temperature Measurement by Microwave Radiometry: Application to Microwave Sintering

IEEE Transactions on Instrumentation and Measurement, 2009
Temperature 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, 2004
Abstract 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), 2002
The 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.

Microwave Radiometry

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

1989
Based 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, 1963
An 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 ...

Microwave radiometry of snow

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, 1987
Microwave 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

Microwave radiometry and applications

International Journal of Infrared and Millimeter Waves, 1995
The radiometry in general is a method of detecting the radiation of matter. All material bodies and substances radiate energy in the form of electromagnetic waves according to Planck s Law. The frequency spectrum of such thermal radiation is determined, beyond the properties of a blackbody, by the emissivity of surfaces and by the temperature of a ...

Passive microwave radiometry over Antarctica

International Journal of Remote Sensing, 1990
Abstract The processing and display of images of Antarctica from data obtained by the Special Sensor Microwave Imager (SSM/I) is described and a general description of ice and snow distribution in Antarctica as observed by the SSM/I is presented.
