Research and development has resulted in a number of unique features that have never before been available, even on large, high seas professional radars. This new technology has been enhanced by the introduction of a new generation of flat TFT screens that provide crystal clear landscape views enabling "two radar displays" to be displayed on one wide screen.Dual Range ModeFor the first time a skipper can select to view a wide screen presentation of a dual range mode, which will enable him to see his immediate area while simultaneously keeping a watchful eye on what is approaching in the distance. This is a major contribution towards the safety of vessels at sea, especially for vessels that do not have two radars fitted. Both ranges are continuously variable, which means that the user can adjust the radar to precisely the ranges required without being restricted by preset range scales.Dual range, night setting During the hours of darkness the Radar can be adjusted to reverse the contrast of the display. This is an important safety feature that reduces light emission from the screen, while accentuating targets and providing continuity of the helms-man's night vision.High Speed UpdateBy using a high speed antenna rotation the update rate of the radar image is doubled. This benefits high speed craft by increasing the target update rate and enabling the dual range function, thereby allowing early detection and tracking of high speed radar targets. This is important with the increasing speed of todays vessels at sea.Semi 3D facility All models have the semi 3D facility. This enables easy and instant discrimi-nation between weak and strong echoes for recognition of small targets and obstacles. This feature is particularly valuable for targets to be seen clearly and naturally for easy recognition.The radars have the facility to show a simultaneous split screen of both conventional and 3D displays. The stunning new landscape screens allow a more panoramic view than other radars and permits the user to make full use of the new, wide screen mode and split screen displays without losing any radar viewing area. By connecting an electronic compass and speed log to the radar via the NMEA input, the True Motion function can be selected. Automatic Tracking Aid The standard ATA board gives a 10 target "mini-ARPA" capability, with target data displayed on screen. The RA50 series radars now includes the ATA function which tracks up to 10 targets designated by the user, manual acquisition, automatic tracking. Once locked on, the radar will automatically provide a menu of data which includes distance and bearing, speed and course and closest point of approach, as well as time on selected targets. A built in alarm system warns of possible collision, lost target, making watch keeping easier and safer.
