Brightness Temperature Computation of Microwave Calibration Targets [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2017
A rigorous numerical technique to compute the brightness temperature of arbitrarily shaped microwave calibration targets is presented. The proposed method allows the brightness temperature of calibration targets to be investigated depending on frequency, absorber material, geometry, antenna pattern, field incidence, and temperature environment. We have

Addendum to: The brightness temperature of Mercury at 150 and 240 GHz

The European Physical Journal Plus, 2012
We present new measurements of Mars at 1.25 and 2mm of wavelength, in addition to the previous ones performed on Mercury and already published in our paper “The brightness temperature of Mercury at 150 and 240GHz”. A brief description of the observational strategy is given, and brightness temperature of the planet is reported.

Brightness Temperature Reconstruction Using BGI

IEEE Transactions on Geoscience and Remote Sensing, 2008
This paper departs from the popular usage of the Backus-Gilbert inversion (BGI) method as a tool for inversion of antenna temperature measurements in microwave radiometry. The BGI method is applied in this paper to enhance the information content of an existing set of oversampled brightness-temperature (TB) data. The purpose is to isolate the inversion

Venus: A Map of Its Brightness Temperature

Science, 1963
The 200-inch Hale telescope has been used to make high-resolution maps of the brightness temperature of Venus at wavelengths 8 to 14 microns. Resolution of about 1/30 of the disk reveals a general symmetry about the plane of the orbit, no day-night temperature effects, and a transient temperature anomaly in the southern hemisphere.

Microwave brightness temperature of snow: Observations and simulations

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
The brightness temperature of snow-covered terrain was monitored from January through April 1985 using tower-based radiometers operating at 1, 16.5, and 37 GHz (vertical and horizontal polarization) in southern Finland. Ground truth data on snow, soil and weather were collected. Layered dielectric, extinction and wetness information on snow at the test

Cloud Model Studies for the Simulation of Brightness Temperatures

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
Two cloud water models that can be included in the radiative transfer to simulate brightness temperatures from radiosonde data are analyzed. We first evaluate and optimize the capability of the models to detect correctly the presence of clouds, by comparing the cloud base heights identified from the radiosoundings with those provided by a ceilometer ...

Brightness temperature of extended targets

ICMMT'98. 1998 International Conference on Microwave and Millimeter Wave Technology. Proceedings (Cat. No.98EX106), 2002
A method of establishing formulas for calculating brightness temperature of extended targets at microwave frequency is introduced in this paper. The formulas are obtained through the statistical process of a large amount of measured data. The formulas for concrete road, asphalt road, and crushed stone are presented, which are established by this method.
