Which term describes the process of combining signals with time delays across the array to steer and focus the beam?

• A. Phasing
• B. Amplification
• C. Damping
• D. Filtering

Answer: (A)

Phasing. In a phased array, you apply specific time delays (phase shifts) to the signals from each element so they combine constructively in a chosen direction. This alignment steers and focuses the beam toward that direction without physically moving the array, creating a sharper, directed signal pattern. Amplification, damping, and filtering perform other signal-processing roles—boosting, reducing, or shaping frequencies—without steering the beam.
