Active and passive means of determining position via radio waves
RAAF AN-FPS-117 radar in 2007
As defined by FS-1037C and ITU Radio Regulations, radiodetermination is:[1]
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:[1]
radionavigation: "used for the purposes of navigation, including obstruction warning", which is mainly active;
radiolocation: "used for purposes other than those of radionavigation", which is mainly passive.
Radar is a radiodetermination system based on the reflection (or retransmission) of a radio wave by an object at a position to be determined.[1]
