  • Patent number: 9817110
    Abstract: The invention relates to a device for detecting objects within a sweep range, comprising at least two switchable transmitting antennas, a plurality of receiving antennas, the transmitting antennas and receiving antennas respectively extending longitudinally, parallel to one another, in a first direction, and the receiving antennas being arranged in a row and the row extending in a second direction, the receiving antennas and the transmitting antennas being arranged such that they produce a synthetic receiving antenna array for the beam sweep by means of the sequential activation of the transmitting antennas and the positions of the transmitting and receiving antennas, the resulting distance corresponding to the positions of the receiving antennas in the synthetic receiving antenna array in the second direction d, the adjacent receiving antennas in the device being spaced apart by a distance of d2 or greater and d2 being twice as great as distance d.

  • Patent number: 9791549
    Abstract: In a method for operating a radar sensor, the unambiguousness range of the radar sensor is increased with respect to the range and/or the relative velocity by: transmitting multiple ramp sets by the radar sensor, the frequency ramps of the individual ramp sets each differing in one system parameter; adapting the sampling frequency during the detection of the radar echoes in such a way that a constant number of samples always results for each frequency ramp; and, to evaluate the radar signals, the spectra are periodically continued and compared to each other.

  • Patent number: 9746554
    Abstract: A radar imaging system and technique is described in which the imaging system generates an image and transforms the image into world coordinates taking into account host position and heading. Once in world coordinates, successive radar images can be summed (integrated, averaged) to produce an integrated image having a resolution which is improved compared with an originally generated image.
