What does electronic FOV gating do?

• A. Ignore information from all lobes.
• B. Compute the relative motion of the target and ignore other lobes.
• C. Retain track by following the flare energy.
• D. Switch to memory mode.

Answer: (B)

Electronic FOV gating relies on motion information to separate a target signal from clutter. By calculating how the target moves relative to the interceptor—how its range and bearing change—you gate processing to the portion of the field of view where that motion signature appears. Returns from other lobes, which don’t share the same motion pattern, are ignored, so the system stays focused on the true target track. This helps reduce false tracks from stationary clutter or off‑axis energy and keeps the track on the target.
