What is signal intelligence?

Signal intelligence, often abbreviated as SIGINT, is the process of collecting and analyzing electronic signals and communications from various sources to gather valuable information. This field plays a crucial role in national security, military operations, and intelligence agencies by intercepting radio, satellite, and other forms of electronic communications. Professionals in this area use specialized technology and methods to detect, interpret, and report on these signals to help inform strategic decisions. SIGINT can provide insights into the intentions, capabilities, and activities of potential adversaries.
