A significant step change in reliable performance


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.


The second generation and patented Constaview™ is realized 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.

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 integrates three different trail length modes that will show a ship’s course instantly, a unique operational feature that allows for more flexibility.

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.

Target enhancement

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. TEF™ works by adding pixels to targets displayed on the radar image and allows a vastly improved degree of discrimination between targets. Sophisticated processing results in a proportional enhancement where the relative enhancement of smaller targets is greater than applied to larger targets.

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.

Theme based navigation

With JRC’s new radar series you don’t have to settle for one constant setting throughout, integrating four navigation themes, facilitating the most optimized radar image, particularly valuable to the dynamically changing conditions. For specific areas, decide on coastal or deep-sea mode and for weather, JRC has a storm and rain mode integrated. JRC-designed themes are easy to customize, so you can adjust and set your radar image exactly as you want.

New keyboard design

With its new case design, the keyboard of the JMA-7100 series allows you to carry out all radar operations simply by using the keyboard or on-screen by use of the trackball. The responsive feel keys allow logical and precise operation and integrates function keys for one-touch access to EBL, VRM, GAIN, SEA and RAIN. This makes it easy to navigate through all common used tasks.

Clear on-screen info

The JMA-7100 series make your radar images more brilliant than ever with a sharp 19-inch high resolution LCD screen. Menu selections, via the keyboard or trackball are clearly shown on the display - allowing “at a glance” interpretation of the radar image. You can also select from multiple background modes e.g. day/dusk/night and adjust the brilliance at your own convenience.

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. Optional TT (Target Tracking) function module with up to 100 targets, and or AIS interface can be built-in.


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.

More built-in ergo-flexibility

The trackball is designed to work in perfect harmony with the operating system. One of the new features in this radar series is that you can effortlessly assign commonly used functions to the left mouse button, giving you the capability to access a preferred function without having to take your hand off the trackball. You can assign and reassign this multi-button with a range of operational features, which among others are AIS info, TT ACQ, show TT data, property, make mark.


Optional interswitching up to 8 displays possible.
