Technology

Which outcome results regarding a phased array antenna when individual element phase shifters exhibit timing drift under stable temperature?

A)Beamforming precision degrades progressively.
B)Sidelobe suppression improves gradually.
C)Overall antenna gain spontaneously increases.
D)Input impedance matching optimizes slowly.

💡 Explanation

Beamforming precision degrades progressively when element phase shifters exhibit timing drift because inconsistent phase relationships introduce beamsteering errors due to mutual interference. Therefore, accuracy reduces rather than optimizing suppression of sidelobes at alternative angles.
