- MRT Maritime Radiobeacon Type
- Definition
- A wide-band beacon that transmits either continuously or periodically on the radar bands and is used to mark maritime navigational hazards.
- Description
- The transmission forms a line of Morse characters on a plan position indicator (PPI) radar display that radiates from the centre of the display to its edge. Periodic transmissions every few seconds are often used so that important radar targets behind the RAMARK beacon are not masked by the Morse characters. RAMARK beacons are less commonly used than RACON beacons which give the location as well as the bearing of the hazard and clutter the radar display less.
