What type of data does ELINT specifically refer to?

ELINT, or Electronic Intelligence, specifically refers to data derived from the interception and analysis of electronic signals. This type of data typically encompasses the analysis of radar and other electronic emissions, providing insights into the capabilities, activities, and intentions of various entities, particularly in a military context. ELINT is crucial for understanding the operational environment and is often used for threat assessment and strategic planning.

While visual intelligence relates to imagery and is important for reconnaissance, it does not encompass the electronic signals that ELINT focuses on. Similarly, geospatial intelligence involves the use of geographic information and imagery, but it does not deal with electronic emissions. Signals intelligence, while partially overlapping in the broader sense of intelligence gathering, is a more encompassing category that includes both ELINT and communication intelligence (COMINT), which specifically pertains to intercepted communications. Thus, ELINT is distinguished as a specific subset of signals intelligence focused on electronic data.
