FURUNO
SOLID STATE DOPPLER RADAR
NXT SERIES
The NXT chapter in Radar
DRS4D-NXT
Radome type
Target Analyzer™ function utilizing Doppler technology spots hazardous targets instantly!
The NXT Radars are the first radars in the world to use FURUNO's exclusive Target Analyzer™ function. Targets that are approaching your vessel automatically change color to help you identify potentially dangerous targets. Green echoes are targets that stay stationary, or are moving away from you, while red echoes are hazardous targets that are moving towards your vessel. Echoes dynamically change colors as targets approach, or get farther away from your vessel. Target Analyzer™ improves situational awareness and can increase safety by showing you which targets to look out for. Additionally, when the rain mode is activated, rain echoes are shown in blue. This mode is particularly useful as it has the capability to detect targets masked by rain clutters.
Target Analyzer™ clearly shows hazardous targets in bright red (Echo trail activated)
Approaching targets are displayed in red
When the rain mode is "on" rain echoes are shown in blue
- Solid-State pulse compression Doppler Radar

Enhanced analytics and improved detection to keep your journey safe
DRS6A-NXT
DRS12A-NXT
DRS25A-NXT
Open array type
*3 antenna lengths: 3.5 ft (XN10A), 4 ft (XN12A), 6 ft (XN13A)
Fast Target Tracking™ and Auto Target Acquire function
With Fast Target Tracking™ activated, it only takes a few seconds for a vector to be displayed once the target is selected, manually or automatically with the Auto Target Acquire function.
When the Auto Target Acquire function is on, approaching targets within 3NM range from own ship, which are potentially hazardous, are automatically acquired by Doppler calculation and will trigger an alarm*. Together, Up to 100 targets can be acquired simultaneously, increasing considerably the safety and simplifying estimation of other vessel's course and speed.
RezBoost™ beam sharpening
FURUNO's exclusive RezBoost™ technology has been incorporated into our Radar units for enhanced resolution and impressive performance. With RezBoost™ set to MAX, the sharpness offers an incredibly detailed image with more targets and less clutter.
Bird Mode
NXT Radars feature a new Bird Mode that helps you identify birds gathering around schools of fish at the sea surface. The Bird Mode adjusts the gain and sea settings automatically for optimal visibility.
