Radars are rarely used alone in a marine setting. A modern trend is the integration of radar with other navigation displays on a single screen, as it becomes quite distracting to look at several different screens. Therefore, displays can often overlay an electronic GPS navigation chart of ship position, and a sonar display, on the radar display ...

The FuMO 24 and 25 (Funkmess-Ortung (Radio-direction finder, active ranging)) were designed as a replacement for the earlier FuMO search radar for Nazi Germany's Kriegsmarine in 1943. The differences between the two models are not clear and it usually used a larger 2-by-6-meter (6 ft 7 in × 19 ft 8 in) antenna than the older system.

Each AIS station determines its own transmission schedule (slot), based upon data link traffic history and an awareness of probable future actions by other ...

A SART will only respond to a 9 GHz X-band (3 cm wavelength) radar. It will not be seen on S-band (10 cm) or other radar. Shipboard Global Maritime Distress Safety System (GMDSS) include one or more search and rescue locating devices. The radar-SART may be triggered by any X-band radar within a range of approximately 8 nautical miles (15 ...
