  • Patent number: 11650305
    Abstract: A vehicle radar system (3) including a control unit arrangement (8) and at least one radar sensor arrangement (4) arranged to transmit signals (6) and receive reflected signals (7). The vehicle radar system (3) acquires a plurality of measured radar detections (10, 11, 12, 13) at different times.

  • Patent number: 11650303
    Abstract: A radar sensor in a motor vehicle has at least one antenna arrangement for emitting and receiving radar signals and a processing device for evaluating received radar signals. The antenna arrangement is controlled to simultaneously emit and receive radar signals both in a far frequency range and in a near frequency range, where the bandwidth of the near frequency range is greater than that of the far frequency range. The received radar signals of the near frequency range are evaluated as radar data of a higher distance resolution and received radar signals of the far frequency range are evaluated as radar data of a lower distance resolution.

  • Patent number: 11644536
    Abstract: A system simulates a moving target for a radar system under test. The system includes a Doppler simulation circuit (DSC), coupled to an input, to apply a frequency shift to RF pulses received on an RF signal to simulate speed. A signal attenuator coupled to the DSC is to simulate signal attenuation due to propagation loss of the RF pulses in atmosphere. A pulse detection circuit is to detect time of receipt of the RF pulses, including a first time of receipt of a falling edge of a first RF pulse. An I/O controller updates a value of the frequency shift for the DSC and of the signal attenuation for the signal attenuator during a time period between the first RF pulse and one of a second RF pulse or a second time at which the second RF pulse should have been received in case of a missing pulse.

As such, the reception antennas of the radar unit may each be configured to receive reflected radar signals that are radiating in one of the four potential polarizations. The radar unit may further include an amplifier configured to cause one or multiple transmission antennas to selectively transmit between two or more of the four polarization channels.

  • Patent number: 11635508
    Abstract: A density of Mode S interrogations and responses in the environment covered by a secondary radar is characterized according to the following steps: a first step wherein the radar: detects and locates Mode S targets by way of their synchronous responses to the interrogations emitted by the radar; detects asynchronous responses emitted by the Mode S targets, and not elicited by the radar; for each target, associates its asynchronous responses with its synchronous response to the radar; a second step wherein the radar: based on the association, determines the response rate of each target by counting the number of synchronous and asynchronous responses received from the target per given time period; with the environment being divided into elementary space cells, determines the response rate per cell by counting the number of synchronous and asynchronous responses received by each target in each cell, the rate characterizing the density of Mode S interrogations per cell.

  • Patent number: 11635489
    Abstract: A method for the use in a radar system is described herein. In accordance with one embodiment, the method includes providing a local oscillator signal to an RF output channel of a radar system. The RF output channel is configured to generate, in an enabled state, an RF output signal based on the local oscillator signal. The method further includes determining a first measurement signal based on the local oscillator signal and a first representation of the RF output signal, while the RF output channel is disabled, and thus the first measurement signal represents crosstalk. Further, the method includes determining a second measurement signal based on the local oscillator signal and a second representation of the RF output signal while the RF output channel is enabled. A phase value associated with the RF output channel is determined based on the first measurement signal and the second measurement signal.
