Which effect is amplified when phased array radars implement beamforming?

A)Constructive interference of electromagnetic waves
B)Reduced thermal noise in the signal
C)Increased impedance of the antenna
D)Improved antenna element radiation resistance

💡 Explanation

The focused signal is magnified via constructive interference of the transmitted signals; this coherent summation leads to a stronger signal in the targeted propagation direction because amplitudes add in phase, rather than other interference patterns.
