Vibrations in automotive radar systems

In the automotive advanced driver assistance systems market there is an increasing trend towards hidden installation of radar sensors. This rises new challenges concerning the sensor's mounting position, fixture and cover. In this paper several types of vibration, which can occur in an automotive environment are classified and their influence on the radar sensor's performance is discussed. A detailed analysis combined with measurement results is given to vibration-induced errors, caused by a relative movement between the radar sensor and its cover.
