What is threat credibility and how is it assessed in CRC?

• A. Threat credibility is not assessed.
• B. It measures the altitude accuracy.
• C. The trustworthiness of a target track based on sensor corroboration, track continuity, and source reliability.
• D. The likelihood of a target being visible on radar.

Answer: (C)

Threat credibility is the trustworthiness of a target track and is used to decide how seriously to treat a detected contact. In CRC, you assess credibility to determine whether a contact represents a real threat and where to allocate resources.

You judge credibility by three main factors. First, sensor corroboration: does more than one sensor agree on the track and its parameters (range, bearing, closure rate)? If multiple sources confirm the same target, confidence goes up. Second, track continuity: does the track remain consistent over time with ongoing updates, or does it appear and disappear or jump erratically? A smooth, continuous history increases credibility. Third, source reliability: how dependable is the sensor or data link providing the track? A proven, well-performing source makes the track more credible than a shaky or untrustworthy one.

Why this matters: credible tracks are prioritized for tracking and potential engagement, while low-credibility tracks are monitored or dismissed to avoid acting on false alarms.

The other options don’t capture this combined assessment. Threat credibility isn’t simply “not assessed,” and it isn’t about altitude accuracy or just whether a target is visible on radar. Credibility comes from corroboration across sensors, persistent track history, and the reliability of the reporting source.
