One-Point Microwave Radiometer Calibration

Polarimetric Microwave Radiometer Calibration

A polarimetric radiometer is a radiometer with the capability to measure the correlation information between vertically and horizontally polarized electric fields. To better understand and calibrate this type of radiometer, several research efforts have been undertaken. 1) All microwave radiometer measurements of brightness temperature (7B) include an additive noise component. The variance and ...

Microwave Radiometer Inter - Calibration : Algorithm Development and Application

Identification of Spaceborne Microwave Radiometer Calibration Sites for Satellite Missions

The first dedicated soil moisture satellite mission will be the European Space Agency's Soil Moisture and Ocean Salinity (SMOS) mission. This satellite, scheduled for launch in the second half of 2009, has a new type of satellite design that is based on the radio-astronomy technique of simulating a large antenna from a number of smaller ones placed some distance apart. Because of its unique des...

Ground-Based Microwave Radiometer Measurements

This particular site and time of year was chosen by ARM because it offers a high probability of clearsky, and also a wide range of integrated water vapor amounts. To supplement the routine observing capabilities during the WVIOP2000, a powerful array of tools for measuring water vapor was deployed at the SGP Central Facility area. A comprehensive suite of airborne in situ and ground-based remote

Camera Self-calibration from One Point Correspondence

The internal and relative orientations of one or more cameras can be obtained by tracking a single point from each of two or more cameras. Thus, for example, a stereo rig can be internally and relatively calibrated by walking around in front of it, or a single camera can be internally calibrated this way using a second camera for data collection. The implications of this fact are important for ...
