Unique features
JRC’s new JMA-7100 ARPA radar series integrates the latest leading technologies and represents a significant step change in terms of reliable performance and cost-effectiveness, making it one of the most advanced radar products available today.
Constaview™
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.

Constaview™
True Trails
Constaview™ refreshes the image every 16mS. Despite heading changes trails are always true.

Relative Trails
Traditional technology relies on several sweeps of the scanner to redraw the image. Trails are presented as relative.
Select a trail length
Other ship’s movement and speed can be monitored from length and direction of their trails, primary serving for collision avoidance. The JMA-7100 radar series integrates three 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:
1 min. |
3 min. |
6 min. |
10 min. |
Target Enhancement Function™
Developed exclusively by JRC, TEF™, allows target enhancement relative to the target size. The smaller echoes are far more enlarged than bigger echoes, giving a better on-screen separation and identification.

Flexible black box configuration
The radars are available in standalone and desktop version to suit your type of vessel. In the desktop version, the processor unit is the heart of the JMA-7100, and shares the same simple configuration as its predecessor, contributing to an enhanced system configuration. TT (Target Tracking) function module with up to 100 targets, and AIS interface are built-in.

Wide dynamic range receiver
The new JMA-7100 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.
More powerful than ever
The JMA-7100 incorporates three Tornado™ processors, which are exclusively developed and designed by JRC, bringing a new level of performance and reliability to radar operation. The new Tornado™ processors, which equal the power of twelve conventional processors, and advanced system architecture make the JMA-7100 series probably the most sophisticated radar available today.
CCRP
As set by IMO regulations, a Consistent Common Reference Point (CCRP) is a location on own ship, to which all horizontal measurements, such as target range, bearing, relative course/speed, closest point of approach, or time to closest point of approach are referenced.
Where multiple antennas are installed, different position offsets for each antenna in the radar system should be applied with respect to the CCRP. If you switch between scanners (up to 8 possible - option), the information displayed is generated allows for consistency and uniform output. This new feature is easily accessible from the menu.
Interswitching
Optional interswitching up to 8 displays possible.
