HIGH RESOLUTION SAR IMAGING EMPLOYING GEOMETRIC FEATURES FOR EXTRACTING SEISMIC DAMAGE OF BUILDINGS
SAR Imaging Geometry Feature Building Seismic Damage Extraction
2018/5/11
Synthetic Aperture Radar (SAR) image is relatively easy to acquire but difficult for interpretation. This paper probes how to identify seismic damage of building using geometric features of SAR. The S...
THERMAL EFFECTS ON CAMERA FOCAL LENGTH IN MESSENGER STAR CALIBRATION AND ORBITAL IMAGING
Mercury, MESSENGER, MDIS Camera Digital Terrain Models
2018/5/11
We analyse images taken by the MErcury Surface, Space ENviorment, GEochemistry, and Ranging (MESSENGER) spacecraft for the camera’s thermal response in the harsh thermal environment near Mercury. Spec...
Geologic imaging technique measures strength of Earth’s outer shell
Geologic imaging technique measures strength Earth’s outer shell
2016/10/10
An advanced imaging technique used to map Earth’s outer shell also can provide a measure of strength, finding weak spots and magma upwellings that could point to volcanic or earthquake activity, accor...
Total electron content - A key parameterin propagation: measurement and usein ionospheric imaging
parameterin ionosphere
2015/9/14
The paper reports on a series of studies carried out within the COST 271 Action relating to the measurement and use of Total Electron Content (TEC) of the ionosphere over North West Europe.
Total ele...
Imaging of the equatorial ionosphere
atmosphere electromagnetic methods remote sensing tomography data processing GPS TEC
2015/9/10
The equatorial anomaly is the dominant structure in free electron concentration in the tropical ionosphere. Due
to its edges (crests) which are characterised by steep latitudinal gradients in TEC and...
Noise modelling and estimation of hyperspectral data from airborne imaging spectrometers
generalised Gaussian probability density function heavy-tailed distributions hyperspectral imagery linear regression noise modelling Visible InfraRed Scanner (VIRS-200)
2015/9/7
The definition of noise models suitable for hyperspectral data is slightly different depending on whether whiskbroom or push-broom are dealt with. Focussing on the latter type (e.g., VIRS-200) the noi...
A new methodology for in-flight radiometric calibration of the MIVIS imaging sensor
hyperspectral airborne scanner MIVIS radiometric calibration data quality
2015/9/7
Sensor radiometric calibration is of great importance in computing physical values of radiance of the investigated targets, but often airborne scanners are not equipped with any in-flight radiometric ...

2015/9/2
The imaging of fast-moving electron-density structures in the polar cap presents a unique set of challenges that
are not encountered in other ionospheric imaging problems. GPS observations of total e...

2014/12/31
Subbasalt imaging can be improved by carefully
applying pre-stack depth migration. Pre-stack depth migration requires a detailed velocity model and an accurate traveltime calculation.
