Specialized applications interpret signals received by antenna arrays to determine the bearing, or direction, from which a radio transmission originates. These tools are essential for locating signal sources, be they intentional broadcasts or unintended emissions. As an example, consider its use in maritime search and rescue, where it assists in pinpointing the location of emergency beacons.
The capability to accurately geolocate transmissions offers significant advantages in various fields. Historically, these methods were instrumental in navigation and military intelligence. Today, such technology finds utility in spectrum management, interference mitigation, and even wildlife tracking. Its precision reduces search times and improves resource allocation.
