DESCRIPTION
JRC’s new JMA-5300Mk2 integrates the latest leading technologies with a set of new features that allows running radar images faster and more efficiently than ever before.
The second generation and patented Constaview™ is realised through the use of three high-speed processors (in-house Tornado™ technology). All info gathered by the radar is fully processed within a few milliseconds before displayed, generating a smooth image rotation when sailing in Head-Up mode. When changing to North-Up, the new radar image is displayed without any delay caused by the scanner rotation.
Other ship’s movement and speed can be monitored from length and direction of their trails, primary serving for collision avoidance. The JMA-5300Mk2 integrates four different trail length modes, that will show a ship’s course instantly, a unique operational feature that allows for more flexibility. Example real-time processing.
The new JMA-5300Mk2 series integrates a wide dynamic range receiver that, compared to conventional models, significantly improves the differentiation of noise and targets under sea clutter. The radar system overcomes different sources of unwanted signals, maintaining a constant level of overall visible clutter.
