A vehicle, a radar system for the vehicle, and method of driving the vehicle. A radar array having plurality of radar nodes is arranged 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 an aperture length of the nodes and a spacing between the nodes is a variable parameter. A processor activates a transmitter of the radar array to generate a test pulse, receive, at a receiver of the radar array, a reflection of the test pulse from an object, and determines an angular location of the object from the reflection of the test pulse. A trajectory of the vehicle can be changed using the determined angular location of the object.
