← ScienceWhich consequence results when a pulsed radar transmitter using a phased array experiences element phase drift?
A)Beam broadening and reduced gain✓
B)Transmitter amplifier thermal runaway
C)Increased side-lobe suppression effectiveness
D)Receiver local oscillator frequency shift
💡 Explanation
Beam broadening and gain reduction occur because phase drift between antenna elements disrupts constructive interference, therefore distorting the far-field pattern, rather than causing amplifier failure because power mismatches occur under phase error.
