  • Publication number: 20220390583
    Abstract: A method for low-interference operation of a plurality of radar sensors, which are installed in different vehicles and each emit a transmission signal in an operating range, which is characterized by at least one of the following parameters: frequency, coding, activity time window. Each radar sensor is assigned an operating range according to at least one degree of freedom of movement of the vehicle, in which the radar sensor is installed.

  • Patent number: 11480653
    Abstract: A method for correcting a radar signal. The method includes the following steps: ascertaining main peaks in the spectrum of the radar signal; determining an auxiliary signal by removing the components of the main peaks in the radar signal; identifying regions of disturbance in the radar signal utilizing the auxiliary signal; and generating a corrected radar signal by interpolating the radar signal in the identified regions of disturbance of the radar signal, utilizing the main peaks through ascertained.

  • Patent number: 11460539
    Abstract: A method for operating multiple sensors of a vehicle in at least partially spatially coinciding detection areas and in a shared frequency domain. In the method, at a transmission point in time, at least two sensors transmit simultaneously on separate instantaneous frequencies separated by a frequency gap, the frequency gap including at least one instantaneous receive bandwidth of the sensors, each instantaneous frequency being blocked for a use by the sensors after the transmission point in time for the duration of a time gap, the time gap including at least one signal propagation time across a reception range of the sensors.
