← ScienceWhich risk increases when phased array radar exceeds bandwidth limitations?
A)Grating lobe propagation worsens significantly✓
B)Maximum antenna gain becomes severely limited
C)Thermal noise becomes overwhelmingly dominant
D)Power amplifier efficiency is drastically reduced
💡 Explanation
Grating lobes appear because destructive interference fails due to limited bandwidth, causing unintended signal propagation therefore signal clarity decreases significantly rather than efficiency diminishing alone, mainly degrading when system bandwidth is exceeded beyond design.
