Apparatuses and methods for two-dimensional beam scanning for determining the position of an object in three-dimensional space are provided. An apparatus comprises a multiplicity of transmitters and receivers, which are arranged orthogonal to one another in an L-, U- or T-shaped structure. In one apparatus, the transmission signals are frequency and phase modulated in combination; and in another apparatus a single frequency carrier signal is subject to binary phase modulation. Here, this is a high-frequency encoding with a great code length, which is generated according to the pseudo-random number principle. The received signals, which include information from all transmitters, are decoded and consequently split into sub-signals, which can be assigned to a two-dimensional virtual array. According to the method of digital beamforming, the individual signals of the virtual antenna elements are formed into a plurality of highly focused beams in the horizontal and vertical direction.

Radar sensor having a two-dimensional beam scan and L-, U- or T- shaped structure for mounting in the region of the front radiator of an automobile

A radar sensor for a vehicle includes a control unit and an antenna array. The radar sensor is configured to perform a three-dimensional scan to determine a vertical and a horizontal position of an object in order to assist with distinguishing the geometrical nature of the object.

Radar sensor, radar sensor system, and method for determining the position of an object using horizontal and vertical digital beam formation for measuring point-reflective and surface-reflective objects

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 (y), and the receiving antennas () being arranged in a row and the row extending in a second direction (x), 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 dor greater and dbeing twice as great as distance d.

Imaging radar sensor with narrow antenna lobe and wide angle-detection range

A device and a method for determining the position of an object, in particular of a moving object, in a three dimensional space is made available. Here the device comprises at least two switchable transmitting antenna arrays having different vertical beam alignments and a number of receiving antennas arranged in a row. The transmitting antennas are arranged spaced apart by a distance that corresponds to the distance between the outer phase centers of the receiving antennas. Otherwise the transmitting antennas can be positioned arbitrarily around the receiving antenna. The horizontal beam sweep over a wide angle range is implemented by the 'digital beam forming' method. The vertical object position is measured by comparing the amplitude of the received signals with sequentially operated transmitting antennas having different vertical beam directions.
