FISINT (Foreign Instrumentation Signals Intelligence)

FISINT, or Foreign Instrumentation Signals Intelligence, refers to the collection and analysis of signals emitted by foreign military or space systems, such as missiles, satellites, and other technologies. This intelligence helps nations understand the capabilities and intentions of other countries by monitoring the operational data and technical information these systems transmit. By analyzing these signals, intelligence agencies can make informed decisions about defense and security matters, providing insights into potential threats and advancements in foreign technology. FISINT forms a critical component of broader intelligence efforts, contributing to national security and strategic planning.
