What is SIGINT?

What is SIGINT?

• A. Signals intelligence from electronic emissions.
• B. Signals intelligence from human sources.
• C. Signals intelligence from meteorological emissions.
• D. Signals intelligence from acoustic emissions.

Answer: (A)

SIGINT is signals intelligence—information collected by intercepting signals transmitted electronically. This includes a wide range of electronic emissions, from voice and data communications to non-communication signals such as radar, navigation, and other transmissions. It’s distinguished from intelligence gathered from people (HUMINT) and from non-electronic data like weather-related or acoustic phenomena. Because SIGINT focuses on electronic signals and their transmissions, describing it as signals intelligence from electronic emissions best captures what it is and how it’s collected.
