← TechnologyWhich risk increases most when an antenna array's elements exhibit inconsistent phase delays?
A)Null steering accuracy degradation✓
B)Adjacent channel power amplification
C)Carrier frequency phase distortion
D)Receiver sensitivity threshold exceedance
💡 Explanation
Null steering depends on precise phase control; inconsistent phase delays disrupt the constructive/destructive interference from each antenna through a `phased array beamforming` mechanism because the intended null locations shift. Therefore, null steering fails, rather than the signal being amplified.
