  • Patent number: 9952320
    Abstract: The invention relates to a method for operating a radar sensor (5, 6) of a motor vehicle (1), in which for detecting a target object (12) in an environment of the motor vehicle (1), a transmit signal (S) is emitted by means of the radar sensor (5, 6) and an echo signal reflected on the target object (12) is received as a received signal, wherein a plurality of sequences (13) each including a plurality of frequency-modulated chirp signals (14) is emitted one after the other by means of the radar sensor (5, 6) as the transmit signal (S), and wherein a transmission pause (15) respectively follows each sequence (13), in which the radar sensor (5, 6) does not emit any chirp signals (14). The period of time of the transmission pauses (15) is respectively randomly adjusted in the operation of the radar sensor (5, 6).

  • Patent number: 9897685
    Abstract: A method for detecting interference in a received signal received by a radar sensor of a motor vehicle is disclosed. For detecting a target object in an environment of the motor vehicle, a transmit signal is emitted by the radar sensor, which includes a sequence of consecutive frequency-modulated chirp signals. The radar sensor then receives an echo signal reflected on the target object as the received signal with the superimposed interference. After receiving the received signal, the interference in the chirp signals of the received signal is detected.

  • Publication number: 20150301157
    Abstract: The invention relates to a method for detecting interference in a received signal (s) received by a radar sensor (5, 6) of a motor vehicle (1) by means of an electronic computing device of the motor vehicle (1), wherein for detection of a target object (12) in an environment of the motor vehicle (1), a transmit signal including a sequence of consecutive frequency-modulated chirp signals is emitted by means of the radar sensor (5, 6) and an echo signal reflected on the target object (12) with the superimposed interference is received, and wherein after receiving the received signal (s) by the radar sensor (5, 6), the interference in the chirp signals of the received signal (s) is detected, wherein for detecting the interference within a chirp signal of the received signal (s), at least one sample of this chirp signal is compared to a sample of another chirp signal of the same sequence, and depending on the comparison, it is determined whether or not at least one of the samples compared to each other is affecte

  • Publication number: 20150260828
    Abstract: The invention relates to a method for suppressing interference in a received signal (s) received by a radar sensor (5, 6) of a motor vehicle (1), wherein for detection of a target object (12) in an environment of the motor vehicle (1), a transmit signal including a sequence of consecutive frequency-modulated chirp signals is emitted by means of the radar sensor (5, 6) and an echo signal reflected on the target object (12) is received as the received signal (s) with the superimposed interference, and wherein after receiving the received signal (s) by the radar sensor (5, 6), the interference of the received signal (s) is detected and suppressed by means of an electronic computing device.
