Method and apparatus for improving noise discrimination using enhanced phase difference value

摘要

Noise distinguish signals from multiple sensors operating in come by extending the phase difference in the signal - axis pickup ( pick-up) is off , on the other hand is improved - is performed by the pick-up so that the axis suppression . Or , in a manner that depends on the phase difference in the signal attenuation / expansion is applied , which is off- axis pickup of suppression and on- axis consistent with the improvement . Rob sensitivity (sensitivity lobe) between you (null) are widened , and as a result improve the directional sensitivity and noise performance distinction narrow lobes .
