Radiodetermination
As defined by FS-1037C, radiodetermination[1] is "the determination of the position, velocity or other characteristics of an object, or the obtaining of information relating to these parameters, by means of the propagation properties of radio waves."
There are two main fields to radiodetermination:
- radiolocation, which is mainly passive
- radionavigation, which is mainly active.
Examples
- Triangulation using radiodetermination
- British Post Office mobile RDF, 1927
- Direction-finding system Galeta Island
- Direction finder with direction-finding aerial
