– performance features

Unique features

JRC’s new JMA-7100 ARPA radar series integrates the latest
leading technologies and represents a signi cant step change in
terms of reliable performance and cost-e ectiveness, 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.

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 di erent
trail length modes, that will show a ship’s course instantly, a unique operational feature that
allows for more  exibility. 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
identi cation.

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 con guration as its predecessor,
contributing to an enhanced system con guration. 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,
signi cantly improves the di erentiation of noise and

targets under sea clutter. The radar system overcomes
di erent 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, di erent
position o sets 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.
