The thesis will focus on radar sensors used in automotive industry, understanding the principle of operation, evaluating their installation and positioning in the front bumper of a car and testing their ability to work in representative scenarios. In particular, the mechanical aspects related to the packaging and installation of the radar sensor will be considered, reasoning about the constraints of the materials and geometry of the radar cover and the bumper. Considerations about the mounting position will be derived from simulations and from the study of the pros and cons of carmaker's solutions. The thesis will deal with analysis of representative scenarios and a corner case, the cut-in maneuver, in which the radar could be, evaluating its ability to perceive the surrounding environment..
