SIMRAD 4G Broadband Radar
For optimal target separation, Broadband 4G Radar is the world’s first dome radar to use Beam Sharpening, which significantly improves azimuth resolution — the effective horizontal beam width of the radar signal. The result is a resolution that is equivalent to a 3. 5?foot, open?array radar. When combined with a Simrad NSE, NSSevo2 NSO evo2 or B&G Zeus2 multifunction display, the system’s user?defined, target?separation control allows users to adjust the level of separation to meet specific navigational needs. The Simrad and B&G Broadband 4G Radars’ exclusive dual?range functionality — available with Simrad NSE, NSO and B&G Zeus displays — makes them the only recreational radars capable of displaying distances from 200 feet to 36 nautical miles — all from a single dome.
The ultimate navigational safety tool, Broadband 4G Radar allows boaters to see a buoy 200 feet away on the multifunction display, while simultaneously monitoring coastal projections up to 36 nautical miles. In addition, Simrad and B&G Broadband 4G Radar models can track up to 10 MARPA targets per range — each with independent control, for a total of 20 tracked targets in split?screen mode.
All Broadband 4G Radars provide an unequalled number of working ranges, 18, for premier performance and navigational awareness. Providing intuitive and easy?to?use operation, each model also features smart, pre?defined Offshore and Harbor modes on all ranges without requiring special tuning knowledge.
Broadband 4G Radar not only raises the bar in radome performance by providing far superior resolution at long?range distances, it also delivers the same exceptional close?range capability signature to Broadband Radar. The system marks objects within 6. 5 feet (2 meters) of the boat, providing target definition and separation in close quarters where traditional pulse radar is blind. Maintaining high?sensitivity and clarity in all weather conditions, the radar provides easy?to?view detail of targets even in high?sea states. Additional Broadband 4G Radar safety and convenience features include: revolution speeds up to 36 rpm foLowrance HDS and Simrad NSS, and 48 rpm for Simrad NSE, NSO and B&G Zeus — providing near?instant updates at ranges less than 2 nautical miles; directional sidelobe?clutter suppression to reduce clutter and echoes Specifications
