How does TACAN generate signals for transmission?

TACAN, which stands for Tactical Air Navigation, generates signals for transmission by producing its own internal signals. This system works by transmitting precise microwave signals that allow aircraft to determine their distance and bearing from a TACAN ground station. The signals are generated through the onboard equipment of the TACAN system, making it fundamentally self-sufficient.

This internal generation of signals is crucial for the operation of TACAN, as it allows for real-time navigation information without the need for external inputs or assistance, distinguishing it from systems that rely on other technologies or manual inputs. Understanding this core function makes it clear why internal signal generation is the correct choice, reflecting the autonomous nature of TACAN navigation technology.
