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
font style='font-size:12px;'>
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.

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)
font style='font-size:12px;'>
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

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.
