Abstract
A radar sensor includes one transmitting antenna, multiple first receiving antennas with the same vertical heights, and a second receiving antenna with a vertical height different from the others. A method for determining the azimuth angle of an object with respect to the radar sensor includes steps of determining an approximation for the azimuth angle in a coarse grid based on the signals of all receiving antennas, and determining the azimuth angle in a fine grid based on the signals of the first receiving antennas in a range around the approximation.
Claims8
A method for determining the azimuth angle of an object with respect to a radar sensor including a transmitting antenna and multiple receiving antennas, a plurality of first receiving antennas of the multiple receiving antennas having the same vertical heights, and one second receiving antenna of the receiving antennas having a vertical height different from the height of the first receiving antennas, and the method comprising:
- determining an approximation for the azimuth angle in a coarse grid based on signals of all receiving antennas;
- and
- determining the azimuth angle in a fine grid based on the signals of the first receiving antennas in a range around the approximation.
A non-transitory computer readable storage medium on which is stored program code for determining the azimuth angle of an object with respect to a radar sensor including a transmitting antenna and multiple receiving antennas, a plurality of first receiving antennas of the multiple receiving antennas having the same vertical heights, and one second receiving antenna of the receiving antennas having a vertical height different from the others, and the program code, when executed by a computer, causing the computer to perform:
- determining an approximation for the azimuth angle in a coarse grid based on signals of all receiving antennas;
- and
- determining the azimuth angle in a fine grid based on the signals of the first receiving antennas in a range around the approximation.
A radar sensor, comprising:
- a transmitting antenna;
- multiple first receiving antennas at the same vertical heights;
- a second receiving antenna at a vertical height different from the height of the multiple first receiving antennas;
- and
- a processing unit to determine an approximation for the azimuth angle in a coarse grid based on the signals of all of the first receiving antennas and second receiving antenna, and the azimuth angle in a fine grid based on signals of the first receiving antennas in a range around the approximation.
