| Course contents : | This Course provides an introduction to spaceborne remote sensing, with emphasis on matter-radiation interactions that determine the observables accessible in each wavelength domain. |
|
| Course objective : | 1)Introduction : what is remote sensing?
2)Observables and types of remote sensing data and instruments, brief history of spaceborne remote sensing (Earth and solar system bodies)
3)Reminder on electromagnetic radiation
Nature of electromagnetic radiation (wavelike vs. corpuscular), matter-radiation interactions, radiometrci and photometric quantities, detection of electromagnetic radiation.
4)Passive observation of solid Earth surface
Interaction mechanisms in VIS/IR, observables, sensors.
Thermal radiation, thermal properties of the solid surface, observables, sensors.
The microwave tail of the Planck curve, the observables, passive microwave radiometers.
5)Active observation of the Earth surface (radars)
Interaction mechanisms, observables, real aperture radar, synthetic aperture radar, altimeter, scatterometer.
6)Observation of oceans
Physical properties o the ocean surface, cartography of the ocean topography using altimetry, determination of surface winds using scatterometry, temperature mapping, phytoplankton mapping.
