← ScienceWhich consequence results when an antenna array's element spacing approaches λ/2 amid heavy radio-frequency interference?
A)Increased grating lobe formation✓
B)Reduced antenna impedance matching
C)Enhanced signal-to-noise ratio
D)Decreased beamforming effectiveness
💡 Explanation
Grating lobes appear because spatial aliasing causes the array factor replicates replicas, therefore producing multiple main lobes rather than single directive beam; rather than signal enhancement or impedance issues occuring.
