METHOD AND CIRCUIT FOR ACCOMMODATING MISMATCH OF A SENSOR ARRAY SYSTEM AND FOR IMPROVED NOISE DISCRIMINATION |
摘要 |
Noise discrimination in signals from a plurality of sensors is conducted by enhancing the phase difference in the signals such that off-axis pick-up is suppressed while on-axis pick-up is enhanced. Alternatively, attenuation/expansion are applied to the signals in a phase difference dependent manner, consistent with suppression of off-axis pick-up and on-axis enhancement. Nulls between sensitivity lobes are widened, effectively narrowing the sensitivity lobes and improving directionality and noise discrimination. |
