Wide-spaced radar nodes with a clear beam pattern

摘要

A vehicle, a radar system for the vehicle, and a method of driving the vehicle. A radar assembly having a plurality of radar nodes is disposed along the vehicle. Each radar node includes a first transmitter at one end of the node, a second transmitter at a second end of the node, and a plurality of receivers aligned between the first transmitter and the second transmitter. At least one of the aperture lengths of the nodes and a distance between the nodes is a variable parameter. A processor activates a transmitter of the radar assembly to generate a test pulse, receives a reflection of the test pulse from the object at a receiver of the radar assembly, and determines an angular position of the object from the reflection of the test pulse. A trajectory of the vehicle may be changed using the determined angular position of the object.
