Abstract
A motor vehicle radar system having at least one sensor-radiation transparent body for focusing the sensor beam and/or at least one radome without intentional focusing in the beam path, at least one arrangement made of electrical printed circuit traces being arranged in the area of the sensor-radiation transparent body and/or the radome, the arrangement being suitable at least for heating the sensor-radiation transparent body and/or the radome, electrical power being able to be supplied to the electrical printed circuit traces, power control of the supplied electrical power being carried out as a function of operating states and ambient conditions, such that the surface temperature (TL) of the sensor-radiation transparent body and/or the radome does not exceed preestablished temperature values.
