Space and astronautical engineering

Imaging radar systems from air- and space-based platform. SAR processing (approximately 2/3 of the course - 40 hours): - basic principles for synthetic aperture radar (SAR) - principles for system design and STRIPMAP, Spotlight SAR, SCANSAR acquisition modes - focusing and auto focusing techniques - geometric distortion correction - SAR images of moving targets - principles and processing techniques for the formation of ISAR (Inverse SAR) images of moving targets Extraction of information from SAR images (approximately 1/3 of the course - 20 hours): - statistical description of speckle noise - despeckling techniques - segmentation techniques - recognition and classification of extended targets - detection of changes and multi temporal patterns - information extraction from multi-dimensional images

Basic knowledge of radar techniques and systems, signal theory.

Majewski, “Spotlight Synthetic Aperture Radar”, Artech House Supplementary material (slides) available on Classroom

Attendance is not mandatory but strongly recommended.

The final exam requests the development of an activity to be done autonomously at home (homework) that includes the development and implementation of the techniques described in the lectures from a theoretical point of view and the analysis of the obtained results. Such activities are conducted by the student using the MatLab programming tools.The examination consists in a talk discussing the implemented procedures and the obtained results using for the talk a PowerPoint presentation (slides collection) describing the work carried out.
