|Language of instruction||English|
|Position within curricula||See TUMonline|
At the end of the module students are able to evaluate radar systems as well as approaches and methods of modern radar technology for location, navigation, and meteorology.

Teaching and learning methods
Teaching method: During the lectures students are instructed in a teacher-centered style. The tutorial lessons are held in a student- centered way. Learning method: In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in exercises and tutorials.
The examination consists of a written examination of 90 min duration. In the written examination, students demonstrate by answering questions under time pressure and with limited helping material (formula summary, non-programmable pocket calculator) the theoretical knowledge of radar principles and algorithms. The final grade consists of the grade of the written exam (100%).
