Measurement and Signature Intelligence (MASINT) is technically derived intelligence data other than imagery and SIGINT. The data results in intelligence that locates, identifies, or describes distinctive characteristics of targets. It employs a broad group of disciplines including nuclear, optical, radio frequency, acoustics, seismic, and materials sciences.

Measurement and Signatures Intelligence (MASINT) is a relatively little-known collection discipline that concerns weapons capabilities and industrial activities. MASINT includes the advanced processing and use of data gathered from overhead and airborne IMINT and SIGINT collection systems. Telemetry Intelligence (TELINT) is sometimes used to indicate data relayed by weapons during tests, while electronic intelligence (ELINT) can indicate electronic emissions picked up from modern weapons and tracking systems. Both TELINT and ELINT can be types of SIGINT and contribute to MASINT.
The Defense Intelligence Agency’s Central MASINT Office (CMO), is the principal user of MASINT data. Measurement and Signatures Intelligence has become increasingly important due to growing concern about the existence and spread of weapons of mass destruction. MASINT can be used, for example, to help identify chemical weapons or pinpoint the specific features of unknown weapons systems. The FBI’s extensive forensic work is a type of MASINT. The FBI Laboratory’s Chem-Bio Sciences Unit, for example, provides analysis to detect traces of chemical, biological, or nuclear materials to support the prevention, investigation, and prosecution of terrorist activities.
