Which is intelligence derived from the interception and analysis of noncommunications emitters (e.g., radar)?

• A. COMINT - communications intelligence
• B. SIGINT - signals intelligence
• C. ELINT - electronic intelligence
• D. FISINT - foreign instrumentation signals intelligence

Answer: (C)

Noncommunications emitters like radar produce signals not used for transmitting voice or data, and the intelligence derived from intercepting and analyzing these emissions is ELINT. This discipline focuses on identifying the emitter, its frequency, waveform, pulse characteristics, timing, and patterns to determine radar capabilities, coverage, and intent. ELINT sits under the broader SIGINT umbrella, which covers all signals intelligence, but it specifically targets non-communication electronic emissions. This is distinct from COMINT, which analyzes intercepted communications, and from FISINT, which deals with telemetry and instrumentation signals from foreign hardware.
