Abstract:
An adaptive sensor array apparatus (100) for generating an output signal in response to received radiation, the apparatus (100) incorporating:(a) multielement receiving means (12) for generating a plurality of element signals in response to received radiation; (b) processing means (32, 34) for processing the element signals to provide corresponding augmented signals in which element signals with and without such processing are grouped; (c) adaptive computing means (38, 136) for adaptively computing weighting vectors from the augmented signals, and for processing the augmented signals using the weighting vectors to provide the output signal, characterised in that the processing means (32) incorporates beamforming means (132) for preconditioning the element signals when generating the augmented signals to enhance interference rejection characteristics of the apparatus (100) when generating the output signal.
