Antenna direction finder
Radio direction finders capture two or more measurements of the same signal, and use the marginal differences between those points to locate the signal’s source.

The origin RDF receivers with the antenna installed onboard ships or aircraft were designed to identify radio sources that provide bearing the Direction Finding (DF) signals. 27-meter (90-foot) diagonal spacing Japanese Adcock direction finder installation for 2 MHz in Rabaul. Frank Adcock originally used the antenna as a receiving antenna, to find the azimuthal direction a radio signal was coming from in order to find the location of the radio transmitter; a process called radio direction finding. The Doppler radio direction finder (RDF) consist of two main components: the RDF processor and the antenna summing unit. The RDF processor performs the signal processing. The antenna summing unit controls the multi-element antenna array. The system supports many possible arrangements of antennas, processors, receivers, and network configurations.
