ABSTRACT:
A multiple output, power inversion adaptive antenna array comprises a number of antenna elements A1-An feeding a cascade beam former structure having groups of decorrelation stages D1.sub.1 -D1.sub.n-1, D2.sub.1 -D2.sub.n-2 etc. The outputs of the first stage in each group are scanned sequentially until the wanted signal is predominant, as determined by a wanted signal recognition CONTROL, at which time scanning of the switch S is halted.
