Abstract
A device for emitting and receiving electromagnetic radiation, in which different antennas are used for the emitting and receiving, a first antenna or first group being used for the transmission in a first polarization form, a second antenna or second group being used for the transmission in a second polarization form, and a third antenna or third group being used for receiving the reflected electromagnetic radiation that was emitted by the first antenna or first group and by the second antenna or second group. The device may be fixed in place on a motor vehicle and used for object detection within the framework of a distance and speed control or a collision avoidance, and the polarimetric information obtained from the different receiving levels during the propagation of the two differently polarized electromagnetic waves via different propagation paths is able to be used for ascertaining a weather-related road condition.
