Basic Concepts of Microwave Radiometry

2020
Super High Frequency (SHF) radiometry began to develop in the 1950s mainly in the former Soviet Union and the United States, with the aim of studying the emission of natural and anthropogenic objects in all weather conditions, the composition of radio-landscapes maps, the development of the recognition methodology for the land and water surfaces and on

Radiative transfer and microwave radiometry

2006
This book chapter gives an introduction to radiative transfer with focus on microwave radiometry. The topics discussed include: Kirchhoff's law of thermal radiation; the radiative transfer equation; and polarisation and Stokes parameters.

Microwave geodesy by interferometric radiometry

Astrophysics and Space Science, 1987
The aim of this paper is to establish a new method-first introduced by Soviet scientists in 1972 —for mapping the Earth in the microwave region passively using the interference pattern which results by correlating the signals from two radiometers which presumably can be mounted in two or more moving satellites.

Applications of satellite microwave radiometry

Advances in Space Research, 1987
Abstract Data from the Scanning Multichannel Microwave Radiometer (SMMR) onboard Nimbus-7 were applied to (a) retrieval of the water equivalent of snow cover, (b) discrimination of forest types and land-cover categories, (c) determination of the near-surface wind speed in the Baltic Sea, and (d) determination of sea-ice concentration in the Baltic ...

Applicatory aerial for microwave radiometry

2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004
We show an opportunity for using a wave conductor for creation of a small-sized applicatory aerial for the measurement of human body temperature. The accounts of aerial parameters are carried out on the basis of oscillatory equations.

Microwave Radiometry At Matra Space

SPIE Proceedings, 1989
Already well-known in optical technology through major space programmes such as the Meteosat IR (Infra-Red) imager and the Spot HRV (High Resolution Visible) camera, Matra has found it necessary to expand the capabilities of their Instrumentation Division in order to match the trend towards passive microwave radiometry.

Quantum Fluctuations in Microwave Radiometry

IEEE Transactions on Microwave Theory and Techniques, 1961
This paper assesses the possible significance of the quantum nature of electromagnetic radiation in limiting the measurement accuracy attainable with a microwave radiometer. Analogies are shown to exist between the form of a formula describing fluctuations in the radiometer output, and both a formula describing the radiometer input signal, and also, a ...
