Evaluation of the Multilook Size in Polarimetric Optimization of Differential SAR Interferograms [PDF]
, 2018 The interferometric coherence is a measure of the correlation between two SAR images and constitutes a commonly used estimator of the phase quality. Its estimation requires a spatial average within a 2-D window, usually named as multilook.

Damage Degree Evaluation of Earthquake Area Using UAV Aerial Image
International Journal of Aerospace Engineering, Volume 2016, Issue 1, 2016., 2016 An Unmanned Aerial Vehicle (UAV) system and its aerial image analysis method are developed to evaluate the damage degree of earthquake area. Both the single‐rotor and the six‐rotor UAVs are used to capture the visible light image of ground targets. Five types of typical ground targets are considered for the damage degree evaluation: the building, the ...

International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 The morphology of vegetation greatly impacts propagation of polarized electromagnetic wave. In order to validate this phenomenon, the mathematical relation between the differential propagation constant of forest vegetation and of its polarized echo is quantitatively derived by using backscattering power profile.

Phase Pattern Calibration for Interferometric Applications in Spaceborne SAR Systems
International Journal of Antennas and Propagation, Volume 2013, Issue 1, 2013., 2013 SAR is a widely used technique to acquire images for geoscience and earth observation applications. Active phased array antennas are commonly used in spaceborne SAR systems. For certain modes and applications, it is necessary to know the phase behavior of these phased array antennas.

Invariant Contrast Parameters of PolInSAR Homogenous RVoG Model [PDF]
IEEE Geoscience and Remote Sensing Letters, 2014 It has been shown that the Cramer-Rao bound (CRB) can be helpful to characterize vegetation and ground height estimations based on the homogenous random volume over ground (RVoG) model and polarimetric interferometric SAR techniques. However, this model is a function of 20 unknown parameters, which makes the performance analysis a tedious task. We show

Indoor Air, Volume 2025, Issue 1, 2025.In indoor offices, it is often difficult to ensure high air quality and thermal comfort. Common problems are low relative humidity and the need for cooling. Previous research has shown that indoor greening can contribute to keeping the relative humidity and temperature at an appropriate level.
