Course unit details:
Fundamentals of Synthetic Aperture Radar (SAR) applied to Environmental Monitoring
|FHEQ level 7 – master's degree or fourth year of an integrated master's degree
|Available as a free choice unit?
LIDAR (Light Detection and Ranging) is a remote sensing technology. LiDAR technology uses the pulse from a laser to collect measurements. These are used to create 3D models and maps of objects and environments. Synthetic Aperture Radar (SAR) images provide day-and-night and weather-independent images. LIDAR and SAR can be used for several applications in the fields of geosciences and climate change research, environmental and Earth system monitoring, change detection, security-related applications and planetary exploration (Moreira et al, 2013).
The course will be focusing on practical classes mainly using R studio and SNAP software freely available from ESA (European Space Agency) and also the freely available images from Sentinel 1 (SAR in C band). Some guest speakers from other institutions will be invited to present their work using SAR image processing and other kind of remote sensing images to monitor and estimate forest and land use and land cover characteristics.
Examples of topics that will be covered include:
1. What is SAR? Brief History of Microwaves
2. Applications of SAR to environment studies
3. Fundamentals of SAR
4. What is LIDAR? Applications of SAR to environment studies
6. Practical classes 1: SAR image processing: Backscattering
7. Practical classes 2 SAR processing: Polarimetry
8. Practical classes 3 LIDAR image processing
9: Practical classes 5: Land use/Land cover change detection
10. Practical classes: Forest structure estimation
Moreira et al, 2013. http://www2.geog.ucl.ac.uk/~mdisney/teaching/teachingNEW/3051/PPRS_7/esa_sar_tutorial.pdf
The unit aims to: give opportunity to the students to learn the principles, techniques, methods of SAR/ LIDAR remote sensing. Different applications of SAR/LIDAR images will be explored with a focus on forest structure (especially biomass and carbon stocks) and land use / land cover monitoring. At the moment with the increasable growth of the Earth Observation (EO) science and industry it is important to offer opportunities to the students to be in contact with advanced technologies in the remote sensing field.
Teaching and learning methods
The classes will be delivered as a mix of lecture and practical. The course material will be delivered via Blackboard
