Abstract: A method for a radar system having a plurality of antennas is provided. The method includes processing a plurality of radar signals for determining a distance between the radar system and at least one target and a velocity of the at least one target, thereby forming a plurality of processed radar signals. Each radar signal of the plurality of radar signals is received by an associated antenna of the plurality of antennas. The plurality of processed radar signals are digitally beamformed for at least one beam direction, thereby forming a plurality of beamformed radar signals. The plurality of beamformed radar signals are summed from the plurality of antennas per beam direction.

Abstract: An automotive radar arrangement includes a radar receiver configured to generate radar reception data from radio signals received by a plurality of radar receive antennas. A radar signal processor is configured to determine an estimate of an angular position of at least one object by processing the radar reception data. A communication interface is configured to receive information about a reference angular position of the at least one object. A determiner is configured to determine a compensation for the radar reception data based on the estimate of the angular position and the reference angular position of the at least one object. The radar signal processor is configured to correct the radar reception data and/or further radar reception data for the detection of a further object based on the compensation. An output interface is configured to provide information about the presence of the further object to a vehicle controller.

Abstract: Systems, methods, and circuitries are provided for calibrating a radar system to compensate for a channel offset. In one example, a method is disclosed for processing radar signals with a radar device. The method includes including receiving respective radar signals from respective virtual receive channels, wherein each virtual receive channel corresponds to a combination of a transmit antenna element and a receive antenna element of an antenna element array. Respective received radar data is generated from the respective radar signals and the radar date is processed to identify one or more stationary objects. Based on the radar data, an estimated radar device motion relative to the one or more stationary objects is determined. A difference between the estimated radar device motion and an expected motion of the radar device is determined and a correction vector is determined based on the difference. The correction vector to is applied to subsequent radar data.

Abstract: In some methods, sampled values based on a reception signal are stored in rows and columns of a memory array. A first 1-dimensional (1D) detector is moved in a first direction over the memory array. The first 1D detector includes a first cell under test and first and second training cells on opposite sides of the first cell under test. The first cell under test and the first and second training cells of the first 1D detector being aligned in the first direction. A second 1D detector is moved over the memory array. The second 1D detector includes a second cell under test and third and fourth training cells on opposite sides of the second cell under test. The second cell under test and the third and fourth training cells of the second 1D detector are aligned in a second direction that is perpendicular to the first direction.

Abstract: A radar system is described. In accordance with one example implementation, the radar system comprises a passive coupler arrangement and also a first radar chip, a second radar chip and a third radar chip. The radar chips each comprise at least one external RF contact and also a local oscillator designed to generate an RF oscillator signal at least in a switched-on state. The external RF contacts of the radar chips are coupled via the coupler arrangement in such a way that, in a first operating mode, the RF oscillator signal can be transferred from the first radar chip via the coupler arrangement to the second radar chip and the third radar chip, and that, in a second operating mode, the RF oscillator signal can be transferred from the second radar chip via the coupler arrangement to the third radar chip.
