Abstract: The present disclosure relates to a concept for detecting radar targets. A plurality of first receive signals is received from first antennas of an antenna array. A first combined range-Doppler map is determined by combining range-Doppler maps of each of the first antennas. First confirmable range-Doppler cells of the first combined range-Doppler map are determined which match a predetermined confirmation criterion. A plurality of second receive signals is received from second antennas of the antenna array. A second combined range-Doppler map is determined by combining range-Doppler maps of each of the second antennas. Second confirmable range-Doppler cells of the second combined range-Doppler map are determined which match the predetermined confirmation criterion. The first and second confirmable range-Doppler cells are combined to obtain a set of confirmable range-Doppler cells. Values of the first and the second combined range-Doppler maps corresponding to the set of confirmable range-Doppler cells are summed to obtain summed values of the combined confirmable range-Doppler cells. Summed values of the total confirmable range-Doppler cells exceeding a predefined selection threshold are selected for target detection.

Abstract: An apparatus for light detection and ranging is provided. The apparatus includes a reflective surface configured to oscillate about a rotation axis, and a plurality of light sources each configured to controllably emit a respective light beam via an optical system onto the reflective surface. Further, the apparatus includes a controller configured to control emission times of the plurality of light sources so that the reflective surface emits a plurality of light beams to an environment according to a first sequence of beam directions for a first measurement, and according to a second sequence of beam directions for a subsequent second measurement.

Abstract: The present disclosure relates to a radar device including a first radar-IC for processing first receive signals from first antennas of an antenna array, wherein the first radar-IC is configured to determine a first range-Doppler map based on the first receive signals, and to determine a first subregion of the first range-Doppler map based on criteria of interest. The radar device also includes at least a second radar-IC for processing second receive signals from second antennas of the antenna array, wherein the second radar-IC is configured to determine a second range-Doppler map based on the second receive signals, and to determine a second subregion of the second range-Doppler map based on the criteria of interest. A data interface is configured to forward information indicative of the first and/or the second subregions to a common processor for further processing.

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.

Abstract: A method for processing radar signals includes emitting a first radar signal via a transmitting antenna of a first radar unit, where the first radar signal is phase modulated using a first code and a first frequency offset is added to at least a portion of the first radar signal, and emitting a second radar signal via a transmitting antenna of a second radar unit, where the second radar signal is phase modulated using a second code. The first code and the second code are orthogonal to each other and the first radar unit and the second radar unit are loosely coupled with each other. The method further includes receiving a combined radar signal via a receiving antenna of the first radar unit, where the combined radar signal comprises a reflections of the first and the second radar signals, and processing the combined radar signal at the first radar unit.

Abstract: A method for the use in a radar system comprises: receiving an RF radar signal; down-converting the received RF radar signal into a base band using a frequency-modulated local oscillator signal including a scanning chirp having a higher bandwidth than a regular chirp bandwidth; generating a digital base band signal based on the down-converted RF radar signal, the digital base band signal including a sequence of samples associated with the scanning chirp; identifying, in the sequence of samples, impaired samples, which are affected by interference; and selecting—based on the position of the impaired samples within the sequence of samples—a sub-band, which has the regular chirp bandwidth, for transmitting chirps of chirp frame used for measurement data acquisition.
