Abstract: A device for generating and/or processing a signal, and a method for ascertaining an adjustment of a device for processing or generating a signal. The method includes the steps: generating a transmission signal or a test signal with the aid of a signal device of a device; separating first signals, which come to the signal device from an interface device of the device, from second signals which come to the interface device from the signal device, the interface device being coupleable or coupled to a transmitting and/or receiving antenna; and outputting the first and the second signals separately from one another.

Abstract: A method for operating a radar sensor, having the steps: sending out a transmit signal; reception, by a receive unit, of the transmit signal reflected by at least one target object; evaluation of the receive signal; and regulation of a cutoff frequency of a high-pass filter as a function of the evaluated receive signal.

Abstract: A radar sensor for driver assistance systems in motor vehicles includes a transmitting and receiving device for transmitting and receiving radar signals, an electronic evaluation device for evaluating the received signals, an electronic control device for controlling the operating functions of the radar sensor, and a self-monitoring device for detecting operating parameters of the radar sensor and for comparing the detected parameters to specific setpoint values, where a control device modifies at least one of the operating parameters and a control circuit controls the parameter to the setpoint value thereof.

Abstract: A method for ascertaining operating data of a radar sensor, including transmitting defined data of a first subsequence of ramp signals to an RF component of the radar sensor; ascertaining the data of the remaining subsequences of the ramp signals from the defined values of the first subsequence with the aid of the RF component; and storing the ascertained data of the remaining subsequences in a first memory of the RF component.

Abstract: A method is described for operating a radar device for a motor vehicle, the method comprising the following steps: Providing operating data of a HF unit of the radar device; Transmitting the operating data of the HF unit via a digital data bus to a microcomputer unit; and Evaluating the operating data of the HF unit with the aid of the microcomputer unit.
