Normality Analysis for RFI Detection in Microwave Radiometry

Remote Sensing, 2009
Radio-frequency interference (RFI) present in microwave radiometry measurements leads to erroneous radiometric results. Sources of RFI include spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the “protected ...

Microwave radiometry in monitoring and emergency mapping of water seepage and dangerously high groundwaters

Journal of Telecommunications and Information Technology, 2023
Detailed and geo-referenced maps identifying the locations of saturated and dry levees can be produced using microwave radiometric measurements from a light aircraft or helicopter, and integrated with GPS for positioning and orientation. The development

Assimilation of vegetation optical depth retrievals from passive microwave radiometry [PDF]

Hydrology and Earth System Sciences, 2020
Vegetation optical depth (VOD) retrievals from passive microwave sensors provide analog estimates of above-ground canopy biomass. This study presents the development and analysis of assimilating VOD retrievals from X-, C-, and L-band passive microwave ...

Sensitivity of GNSS-R spaceborne observations to soil moisture and vegetation [PDF]

, 2016
Global navigation satellite systems-reflectometry (GNSS-R) is an emerging remote sensing technique that makes use of navigation signals as signals of opportunity in a multistatic radar configuration, with as many transmitters as navigation satellites are

Microwave remote sensing of water vapor in the atmosphere [PDF]

Geographica Helvetica
Water vapor in the atmosphere plays a crucial role in climate and in atmospheric processes. Due to its long chemical lifetime it can be used as a tracer for investigations of dynamical processes in the middle atmosphere.

Mapping the CMB II: the second flight of the QMAP experiment

, 1998
We report the results from the second flight of QMAP, an experiment to map the cosmic microwave background near the North Celestial Pole. We present maps of the sky at 31 and 42 GHz as well as a measurement of the angular power spectrum covering the l ...

Dynamic Bayesian Nonlinear Calibration [PDF]

, 2014
Statistical calibration where the curve is nonlinear is important in many areas, such as analytical chemistry and radiometry. Especially in radiometry, instrument characteristics change over time, thus calibration is a process that must be conducted as ...

Thermal dosimetry for bladder hyperthermia treatment. An overview. [PDF]

, 2016
The urinary bladder is a fluid-filled organ. This makes, on the one hand, the internal surface of the bladder wall relatively easy to heat and ensures in most cases a relatively homogeneous temperature distribution; on the other hand the variable volume,
