Radio direction finders enable the direction to a transmitter to be estimated. This is sufficient in some applications such as traffic control. In all other applications listed above, the location of the transmitter of interest must be known.
There are various methods of finding a transmitter of interest:
- Triangulation (AOA)
- Time difference on arrival (TDOA)
- Power difference on arrival (PDOA)
- Homing/running fix
In order to find the best radiolocation solution for your application, it is important to understand the advantages, disadvantages and limits of each of these methods.
