PHASE STABILIZATION IN ADAPTIVE ARRAYS

摘要

A phase-stabilized adaptive array system and method including a moving antenna array (54A-54N), a plurality of signal channels (52A-52N) coupled to the antenna array, each for producing a channel signal, each channel including adaptive signal weighting apparatus (60A-60N) for weighting the channel signal by a channel weight. The system further includes combining apparatus for combining the weighted channel signals to form a beam signal, and phase compensation apparatus (66) for applying phase compensation weights to the array signals or the beam signal which vary in dependence of the beam scan position such that the response to a signal at a known direction is held substantially constant while the antenna is moved, or as the weights are updated.
