摘要： A system in a vehicle includes a radar system with a uniform linear array (ULA) of antenna elements and a uniform rectangular array (URA) of antenna elements to receive the reflected signals resulting from the emitted radio frequency energy. The ULA is arranged perpendicular to the URA. Processing circuitry estimates one or more elevation angles using the reflected signals received by the ULA of antenna elements and estimates an azimuth angle corresponding to each of the one or more elevation angles using the one or more elevation angles and the reflected signals received by the URA of antenna elements. Each of the one or more elevation angles and the corresponding one of the azimuth angles is referred to as an angle of arrival (AOA) of the reflected signals from an object. Control of an operation of the vehicle is based on each AOA of each object.

摘要： Aspects of the present disclosure are directed to radar signal processing apparatuses and methods. As may be implemented in accordance with one or more embodiments, digital signals representative of received reflections of radar signals transmitted towards a target are mathematically processed to provide or construct a matrix pencil based on or as a function of a forward-backward matrix. Eigenvalues of the matrix pencil are computed and an estimation of the direction of arrival (DoA) of the target is output based on the computed eigenvalues.

摘要： A computer implemented method for determining an angle of a detection comprises the following steps carried out by computer hardware components: acquiring a range rate of the detection; determining a pair of candidate angles of the detection based on the range rate; acquiring a beamvector of the detection; determining a correlation between the beamvector and a reference vector; and determining the angle of the detection based on the pair of candidate angles and based on the correlation.

摘要： An RFID tag reading system and method estimate bearings of RFID tags. When the RSSI of a primary and/or secondary RFID receive signal is below a threshold, a primary receive beam is steered in a limited scan to an array of locations distributed around the location at which the RSSI of the primary receive signal is a maximum, and the RSSI of the primary receive signal is recorded at each location. The recorded RSSIs are processed to determine an effective weighted center of distribution of the recorded RSSIs, and the bearing for the tag based on the weighted center of distribution is thus estimated.

摘要： Disclosed are a sensor, the vertical alignment of which can be adjusted, and a vertical sensor-alignment adjustment apparatus using the same. In particular, in order to allow the vertical alignment to be adjusted, the sensor has a construction including a plurality of switchable transmitting antennas or a plurality of switchable receiving antennas or a construction including a tilting motor for adjusting an transmitting angle or a receiving angle. The vertical sensor-alignment adjustment apparatus employing such a sensor determines whether the sensor is misaligned in terms of its vertical alignment, and corrects the vertical misalignment of the sensor by executing variable switching to one of the transmitting antennas, by executing variable switching to one of the receiving antennas, or by controlling the tilting motor, so that the transmitting angle of sensor signals or the receiving angle of reflected waves for the sensor signals can be adjusted.
