Signals Intelligence, often abbreviated as SIGINT, refers to the collection and analysis of electronic signals and communications. This includes data from various sources such as radios, telephones, and satellites. The primary goal of SIGINT is to gather information that can help in national security, military operations, and intelligence assessments. SIGINT is divided into two main categories: Communication Intelligence (COMINT), which focuses on intercepted communications, and Electronic Intelligence (ELINT), which deals with non-communication signals, such as radar emissions. By analyzing these signals, intelligence agencies can gain insights into the activities and capabilities of potential adversaries.
