Name a primary data source used to verify a target track before interception.

• A. Cross-sensor track corroboration (radar data from multiple sensors) and IFF confirmation.
• B. A single radar track validated by controller observation.
• C. Optical target sighting through ground observers.
• D. Weather radar data only.

Answer: (A)

Verifying a target track before intercept relies on cross-sensor corroboration—radar data from multiple independent sensors that converge on the same track—combined with IFF confirmation to positively identify friend or foe. This approach provides independent evidence of the target’s position and motion from more than one sensor, and adds identity data that helps distinguish legitimate targets from decoys, clutter, or false echoes. It reduces the risk of reacting to a single-sensor error and speeds up a confident intercept decision.

Relying on a single radar track validated by controller observation is weaker because it depends on one sensor and human interpretation, which can be slower and more prone to error. Optical target sighting through ground observers is limited by line of sight, range, weather, and rapid target movement, making it unreliable as the primary verification source. Weather radar data alone doesn’t identify a specific aircraft and can be confused by weather returns, so it isn’t suitable for confirming a track.
