Abstract
The invention provides an adaptive sensor array apparatus ( ) incorporating a multielement antenna ( ) for receiving radiation from a scene ('S') and generating signals (e) in response thereto and a processing unit ( ) for processing the signals (e) to provide an output signal (y). The unit ( ) comprises an adaptive weight computer ( ) arranged to generate weighting vectors (w) which are used in the unit ( ) to attenuate contributions to the output signal (y) arising from sources of jamming radiation in the scene and transmit contributions to the output signal (y) arising from wanted targets therein. The apparatus ( ) incorporates a non-adaptive beamformer unit ( ) for preconditioning the signals (e) before they are passed to the computer ( ). Preconditioning the signals (e) enhances performance of the apparatus ( ) relative to conventional adaptive sensor array apparatus ( ).
