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 ...
متن کاملAutomatic Calibration of HEC-HMS Model Using Multi-Objective Fuzzy Optimal Models
Estimation of parameters of a hydrologic model is undertaken using a procedure called “calibration” in order to obtain predictions as close as possible to observed values. This study aimed to use the particle swarm optimization (PSO) algorithm for automatic calibration of the HEC-HMS hydrologic model, which includes a library of different event-based models for simulating the rainfall-runoff pr...
متن کاملCalibration of the AIRS microwave instruments
Aqua carries three microwave radiometers that form an integral part of the Atmospheric Infrared Souding (AIRS) sounding suite. Two Advanced Microwave Sounding Unit-A modules, one operating with two channels in the 23–31-GHz range and one operating with 12 channels in the 50–60-GHz range and one channel at 89 GHz, provide all-weather temperature soundings and cloud information. The Humidity Soun...
متن کاملCalibration of Microwave Radiometers: an Overview
INTRODUCTION This paper describes 1) the progress of the work of the IEEE Geoscience and Remote Sensing Society (GRSS) Instrumentation and Future Technologies Technical Committee (IFT-TC) Microwave Radiometer Working Group and 2) an overview of the calibration issues of microwave radiometers as an introduction to a dedicated session.
متن کاملAutomatic Marker Field Calibration
In many augmented reality applications a marker field (set of markers) is used to define the 3Dcoordinate transformation between the camera and the virtual objects. In most systems, the physical positions and pose of each marker relative to each others need to be measured in advance. This calibration process is often time consuming and inaccurate if done by hand. We present an automatic calibra...
