Specific course objectives

Basic knowledge of remote sensing, of the essential structure of remote sensing instruments to perform remote sensing from terrestrial, airborne, spaceborne platform, and of data produced by the different remote sensing systems, and finally of the use of remotely sensed data. Capability to recognize data from the different sensors; basic capability to select the most advisable sensor for a given application and set of conditions.

Course programme

The Remote Sensing Systems course aims at providing to the student some basic knowledge about systems to performe (mainly spaceborne) remote sensing in an Earth Observation perspective. Specific emphasis is placed on Synthetic Aperture Radar. The produced data is also treated, as well as some techniques for their processing.

Physical principles of remote sensing
What is remote sensing and what it is based on. Earth Observation from satellite.

• What is Remote Sensing.
• The remote sensing vehichle: electromagnetic waves, their generation, the black body.
• Principles of Remote Sensing: interaction of electromagnetic waves with surfaces and the atmosphere
• Remote sensing systems: platforms and sensors, classification and relevant features.

Optical remote sensing systems
Systems for remote sensing at the optical frequency range.

• Optical remote sensing.
• Mono-spectral (panchromatic), multispectral, hyperspectral remote sensing.
• Photography and scanning.
• Examples of optical remote sensing systems.

Radar Remote Sensing Systems
Microwave-based remote sensing systems

• Microwave remote sensing.
• The main active, imaging microwave sensor: the EO radar.
• The pulse compression technique.
• Synthetic Aperture Radar (SAR): operation principle.
• Synthetic Aperture Radar (SAR): imaging.
• Radar Polarimetry
• Radar Interferometry
• Spaceborne radar sensors onboard ENVISAT, ERS, Seasat, RADARSAT.
• The Italian very high resolution radar constellation: COSMO/SkyMed.
• Basic concepts on weather radar.

Remotely sensed data
What the acquisition produces. Connected issues and processing techniques.

• Data format and look
• Distortions in optical data
• Distortions in radar data
• Basics of data processing

Other remote sensing systems
Some basic elements on other remote sensing systems.
