| AT76.28 : Principles and Application of InSAR 1(1-0) | ||||
| Course objectives: | ||||
The objectives of this course are: i) to provide background knowledge and understanding of principles of InSAR; iii) to acquire skills on basic InSAR and DInSAR image processing and analysis as well as basic knowledge on main limitations and error sources of these techniques; iv) to enable critical, spatial and temporal thinking on InSAR for real-world applications |
||||
| Learning Outcomes: | ||||
The students on the completion of this course would be able to:
1. Evaluate critically the principles of INSAR and DInSAR systems
2. Search and download relevant SAR data required for a certain InSAR and DInSAR –based project/purpose.
3. Perform basic signal processing techniques for InSAR and DInSAR imaging using publicly available software packages and SAR data.
4. Visually interpret in a qualitative way InSAR and DInSAR output images and interferograms.
5. Gain insight into the strengths and limitations InSAR and DInSAR systems and applications.

| Time Distribution and Study Load: | ||||
Lecture: 10 Hrs
Tutorials: 15 Hrs
Self-study: 40 Hrs
|
||||
| Teaching and Learning Methods: | ||||
1. Lectures: Students will receive lecture notes and the weekly lecture schedule at the beginning of the course. They will be requested to read the lecture notes before coming to the class.
2. Tutorials: Tutorials will expose students to different tools in SAR imaging. Instructor will provide a basic guideline for student to learn and familiarize with Radar Interferometry software and data. Students are requested to understand the algorithm of each operation so that they are able to operate with other software. Students will be requested to complete home assignments and submit a report in due time.
3. Discussion Sessions: Every class will have discussion sessions to engage all the students.

| Evaluation Scheme: | ||||
Tutorials: 50%
Final exam (closed book): 50%
The final grade will be based on the following weight distribution: tutorials (50), final exam (50%). An “A” would be awarded if a student can elaborate the knowledge learned in class by giving his/her own analysis on real case examples given in this course and from journal articles and including assigned readings. A “B” would be awarded if a student shows an overall understanding of all given topics, a “C” would be given if a student meets below average expectation on both knowledge acquired and analysis. A “D” would be given if a student does not meet basis expectations in understanding and analyzing the topics and issues presented in the course.
