Intelligence derived from non-communications systems like RADAR and navigation aids is known as?

The correct answer is Electronic Intelligence (ELINT) because this term specifically refers to intelligence gathered from non-communications electronic systems, which include radar and navigation aids. ELINT focuses on the detection, analysis, and exploitation of electronic signals that are not related to communications, such as signals from radar systems used in various military applications.

This type of intelligence is crucial for understanding enemy capabilities and operations, as it allows analysts to gather valuable information about the systems in use, including their range, capabilities, and potential vulnerabilities. ELINT helps in assessing threat levels and planning countermeasures in electronic warfare scenarios.

Operational Electronic Intelligence (OPELINT) generally relates to the operational aspects of electronic warfare, but it doesn't specifically focus on the radar and navigation aids that ELINT targets. Technical Electronic Intelligence (TECHELINT) tends to involve more detailed technical assessments of a specific system's functionalities and designs rather than the broader signal intelligence gleaned from systems like RADAR. Communication Intelligence (COMINT) specifically deals with communication systems, making it distinct from ELINT's focus on non-communications electronic signals.
