Cut the clutter
Detect targets at very close proximity to your vessel, or at very long ranges to see distant vessels, land features and even weather fronts. Distinguish targets through even the heaviest rain clutter.
Use the radar to see the weather coming, then use the radar overlay to map the weather pattern onto the chart.
Not everything transmits AIS!
Using MARPA* (mini-automatic radar plotting aid) allows you to identify vessel, speed, bearing, closest point of approach (CPA) and time to closest point of approach (TCPA), dangerous/proximity alarms, overlay AIS info for further target clarification.
*For the best radar overlay and MARPA performance fit a smart heading sensor or an SPX autopilot course computer.
Target (1) has been aquired (red circle overlay) using MARPA and is being tracked by your radar. Speed and bearing of the target are shown and the target's heading is shown as a thin red line at 65º (2).
The tracked target has now moved into the previously set guard zone around your vessel and has triggered the dangerous target alarm, seen on screen, and set off an audible alarm
The alarm has been acknowledged and the target's (1) (now overlaid with a red triangle to note possible danger) closest point of approach (CPA) to your vessel is shown on screen as 0.376nm (3) and time to closest point of approach (TCPA) is 4 mins 20 secs (2).
