Abstract
The invention refers to a method and a system for enhancing the measuring accuracy in an antenna array (1), where the method comprises the steps of; a) receiving analog signals on all antenna elements (2) at a first time t1; producing first values for a first radiation diagram from the values in the signals from the first time (t1), and; finding the maximum point (8) for the first values, b)—reducing the signal from one interadjacent antenna element (2) at a second time (t2); receiving analog signals on all antenna elements (2) 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 (t2); c) rejecting all values outside a first range (9) calculated from the first values, and; finding the maximum point (8) for the second values.
