If the antenna array is oriented in a way that is not in-line with the vehicles axis of movement, then you can set the offset here. This is most useful for linear arrays that might be oriented along the front-back axis of a vehicle, as zero degrees for a linear array is orthogonal to the array. So in that case it would need to be rotated 90 degrees to be aligned with the vehicles axis of movement.
