Radiogoniometry, also known as direction finding or radio direction finding, is a technique used to determine the direction of a radio signal. It involves the use of a specialized device called a radio direction finder (RDF), which is capable of detecting and measuring the strength of radio signals from different directions.
There are several methods of radiogoniometry, including:
Amplitude Comparison: This method compares the amplitude of the signal received by two or more antennas, each placed at different locations. By comparing the amplitudes, the direction of the signal source can be determined.
Time Difference of Arrival (TDOA): In this method, the time difference between the arrival of the signal at two or more antennas is measured. By calculating the difference in arrival time, the direction of the signal source can be determined.
Phase Comparison: This method compares the phase of the signal received by two or more antennas. By comparing the phases, the direction of the signal source can be determined.
Radiogoniometry has a variety of applications, including in navigation, search and rescue operations, and military operations. It is also used in amateur radio and in the study of radio propagation.
