Introduction
Remote Sensing (or Earth Observation) concerns sensing of properties of the surface and the atmosphere of the Earth bymeans of air- or spaceborne sensors utilizing electromagnetic radiation. Remote sensing techniques are well-suited for measuring parameters that are important in the monitoring of the Earth's climate and environment, i.e. parameters such as ice glacier extent and dynamics, sea ice extent, extent of deforestation, sea surface temperature, and ozone content in the atmosphere.
Aim
The course aims at a general introduction to techniques used in remote sensing with emphasis on microwaves, and with some emphasis on the technical description of the sensors in order to further the understanding of for example advantages and limitations by using a certain technique.
Content
The content of the course is directly related to the remote sensing research that has developed at EMI through more than 30 years, and results from this research are used as examples in the course. The following subjects are covered:
- Visible and infrared techniques
- Imaging radar techniques, including Synthetic Aperture Radar (SAR)
- SAR Interferometry
- SAR Polarimetry
- Surface and Volume scattering and Applications.
- Ocean sensing: radar altimetry and scatterometry
- Microwave radiometer (MWR) techniques
- MWR Applications, e.g. ocean salinity, soil moisture and sea ice
- Atmospheric sensing, microwaves and millimetre waves
Format
The above-mentioned subjects will be presented in a number of lectures. In addition, students will carry out a project in teams of 2 to 3 students. These projects may cover one of the above subjects, and they can involve e.g. programming of algorithms and/or investigation of remote sensing data. The projects will run through the major part of the course, and they are terminated by a brief report and a presentation at a seminar.
Prerequisites
Students are expected to have basic knowledge of electromagnetic theory and of system components, as for instance obtained through 31405 Wireless Communication. Basic knowledge of statistics, signal analysis, and programming will be an advantage.
Evaluation
The evaluation is based on a project report (weight 1/3) and an oral examination (weight 2/3)
