MASINT

MASINT, or Measurement and Signature Intelligence, is a type of intelligence gathering that collects and analyzes unique signals or physical characteristics from sources like sensors, satellites, or devices. Unlike traditional spying or photography, MASINT detects specific "signatures"—such as heat, chemicals, or sound—to identify and monitor objects, activities, or targets. It helps military and security entities understand threats, track equipment, or monitor environmental conditions without direct observation. In essence, MASINT reveals hidden details by measuring the distinctive signals objects emit or reflect, providing valuable insights that complement other intelligence methods.
