摘要： A radar system for detecting the environment of a motor vehicle includes an antenna assembly comprising plastic and including one or more individual antennas for transmitting and/or receiving radar signals. A circuit board includes at least one area that is permeable by radar waves. At least one high-frequency component is coupled to one side of the circuit board and includes at least one radiating element for direct emission or receipt of radar waves in the direction of the circuit board in the least one area that is permeable by radar waves. The antenna assembly is disposed on the other side of the circuit board opposite the at least one high-frequency component. The antenna assembly includes a coupling/decoupling point disposed in the at least one area of the circuit board permeable by radar waves.

摘要： A method for detecting the environment of a motor vehicle utilizing a radar sensor includes bringing about frequency modulation with a controllable oscillator and generating a sequence of transmission-frequency-modulated transmit signals, which each have the same nominal frequency profile. Received signals reflected from objects are evaluated such that an actual profile of the transmission frequency within the transmit signals or a deviation of the actual profile from the nominal frequency profile is established. Depending on an actual profile and/or a deviation determined, correction in the driving of the oscillator and/or correction in the evaluation of the received signals and/or adaptation of the driver assistance function and/or the autonomous driving maneuver function up to and including disabling thereof are performed.

摘要： A method for controlling a radar system is presented, for detecting the surroundings using transmission means for emitting transmission signals which contain a sequence of at least approximately identical individual signals, the sequence of individual transmission signals being repeated cyclically, said method being characterized in that over the sequence of the individual signals the frequency position thereof—optionally apart from a varying and at least approximately mean value-free component—is changed at least approximately linearly and, in the process, the slope of the linear frequency position change over the individual transmission signals is at least sometimes varied from sequence to sequence, in particular in order to increase the radial distance and/or relative speed measurement accuracy and/or in order to be more robust in respect of interference with other radar systems.

摘要： A radar system for detecting the surroundings of a motor vehicle, the radar system includes a plastic-based antenna having a front side facing a cover. The plastic-based antenna has a plurality of individual antennas for transmitting and/or receiving radar signals to detect objects and/or determining angles thereof. The front side between the individual antennas is configured to be at least partially not reflective on a surface thereof such that interference waves on the surface of the plastic-based antenna and/or reflections between the plastic-based antenna and the cover are suppressed or the negative effects thereof on the determination of angles are at least reduced.

摘要： A method for detecting the environment of a motor vehicle utilizing a radar system includes bringing about frequency modulation utilizing an oscillator and generating a sequence of transmission-frequency-modulated transmit signals, which each having the same nominal frequency profile, apart from a variation in frequency position. Received signals for object detection are evaluated. A one time-discrete signal per transmit signal is used which includes information about the frequency profile of the transmit signal and which is generated by sampling of an analog signal or by reading out of a free-running counter at predetermined points in time. These time-discrete signals are unnormalized by way of the transmit signals with regard to the position of their phase and/or their initial value.
