Abstract
The invention refers to a method and a system for enhancing the measuring accuracy in an antenna array (), where the method comprises the steps of; a) receiving analog signals on all antenna elements () at a first time t; producing first values for a first radiation diagram from the values in the signals from the first time (t), and; finding the maximum point () for the first values, b)—reducing the signal from one interadjacent antenna element () at a second time (t); receiving analog signals on all antenna elements () except from the one switched off or reduced antenna element, and; producing second values for a second radiation diagram from the values in the signals from the second time (t); c) rejecting all values outside a first range () calculated from the first values, and; finding the maximum point () for the second values.
