Radioelectric propagation in open space and above ground
This training will enable the engineers concerned by the major fields of application of electromagnetism (telecommunications, radar, satellite navigation, electronic warfare ...) to have an overview of the problems of propagation of radio waves and to be able to to understand the physics.
The internship presents many applications of propagation models to the study of these systems either to optimize their performance or use, or to adapt them to the propagation conditions.
The course lasts 5 days (30 hours) and includes:
- 20 hours of lectures with theoretical principles and applications
- 10 hours of exercises
The course is structured around 2 related areas:
- An analytical look at each propagation phenomenon focused on understanding the mechanisms in order to evaluate their influence on a propagation assessment in various environments.
- A look at systems as a whole, combining individual phenomena in order to better understand performance limitations due to propagation and to optimize the performance of these systems.
Engineering design and demonstrations of software tools integrating and modeling the multiple aspects of propagation illustrate these different areas and promote dialog among learners.
Helpful if also taking courses ELA 006, ELA 007, ELA 013, ELA 024 and SYS 036.
Course level: Basic
To fully benefit from this course, we recommended general knowledge of the propagation conditions of electromagnetic waves either in free space or on application systems and the processing of the corresponding signals.
