Obiettivi dell'insegnamento
Radar imaging is used for mapping the Earth surface from above. Applications include land-use characterization, forestry, topographic mapping, hazard monitoring, measurement of surface deformation (e.g.: earthquakes, landslides, land subsidence), ice drift velocity. The course will present the basics of passive and active electromagnetic remote sensing, and will introduce students to the use of radiometers, hyperspectral and optical systems. Radar systems will be treated in detail, considering ground, airborne, and spaceborne systems for Earth Observation.
The course is complemented with field lessons, computer lab sessions and presentation of case studies.
