ABSTRACT:
The ratio of useful-signal power to the power of interference signals at an antenna (ANT) having plural sensors, and at least one sensor is obtained by filtering the antenna output signal with a filter having a transfer function (W(t), W(t, f)) equal to the ratio of two linear functions of the power ({circumflex over (p)}y(t), {circumflex over (p)}y(t, f)) at the output of the antenna to the power {circumflex over (p)}x(t), {circumflex over (p)}x(t, f)) at the input of the antenna (ANT).
