- MRT Maritime Radiobeacon Type
- Definition
- A type of radar transponder commonly used to mark maritime navigational hazards.
- Description
- When a RACON receives a radar pulse, it responds with a signal on the same frequency that leaves an image on the plan position indicator (PPI) radar display that radiates from the centre of the display to its edge. This takes the form of a short line of dots and dashes forming a Morse character radiating away from the location of the beacon, the length of the line usually corresponding to the equivalent of a few nautical miles on the display.
