METHOD AND MIMO RADAR DEVICE FOR DETERMINING A POSITION ANGLE OF AN OBJECT

摘要

A method and a MIMO radar device are provided for determining a position angle of an object. The method includes the following steps: emitting a first radar signal with the aid of a first transmitting antenna having a first radiation pattern; emitting a second radar signal with the aid of a second transmitting antenna having a second radiation pattern; emitting a third radar signal with the aid of a third transmitting antenna having a third radiation pattern; the first, second, and third radar signal being emitted in various directions; receiving radar signals which are reflected on the object; and determining the position angle of the object based on phase differences and based on amplitude differences, which originate from the emission of the radar signals in the first through third directions, between the received reflected radar signals.

1. A method for determining a position angle of an object, comprising:
emitting a first radar signal via a first transmitting antenna having a first radiation pattern; emitting a second radar signal via a second transmitting antenna having a second radiation pattern; emitting a third radar signal via a third transmitting antenna having a third radiation pattern, wherein:
a main lobe of the first radiation pattern points in a first direction,a main lobe of the second radiation pattern points in a second direction which is at a first angle of between 1 degree and 90 degrees relative to the first direction, anda main lobe of the third radiation pattern points in a third direction which is at a second angle of between 1 degree and 90 degrees relative to the second direction; receiving radar signals reflected on the object; and determining the position angle of the object based on phase differences and based on amplitude differences that originate from the emission of the radar signals in the first through third directions, between the received reflected radar signals.
