Abstract
A method and apparatus for removal of a parasitic coupling of a signal source to an output of an antenna array comprising at least one antenna element connected via an associated controllable switch to a signal receiver connected to the output of said antenna array, the method includes measuring a parasitic coupling signal received by the signal receiver connected to the output of said antenna array while all switches of the antenna array are switched off and a first reference signal received by a reference signal receiver; measuring a total reception signal for each antenna element and a second reference signal; calculating a parasitic coupling free reception signal for each antenna element by subtracting a ratio between the measured parasitic coupling signal and the measured first reference signal from a ratio between the total reception signal.
