Bright and Clear 15-Inch Display
This radar features a 15-inch color LCD screen with LED backlighting and 32-bit TFT technology. It delivers crystal-clear visuals, ensuring optimal performance even in poor visibility. Whether you’re navigating in fog, darkness, or heavy rain, this display keeps your surroundings in view.
Advanced Target Tracking and AIS
Thanks to ARPA (Automatic Radar Plotting Aid), the system can automatically track up to 20 moving targets, improving your situational awareness. In addition, AIS integration allows you to identify vessels in real time by displaying information such as vessel name, MMSI, speed, and direction. These features help you avoid collisions and make smarter decisions at sea.
Flexible Range and Viewing Modes
The KR-1568 supports a wide range scale from 0.125 to 72 nautical miles, with customizable range intervals and up to 6 range rings. You can choose from multiple display modes—Head-up, Course-up, and North-up—for the view that suits you best.
Powerful Performance in Any Condition
This radar system operates at a peak output power of 6 kW, delivering strong and stable pulses. Its 1.2-meter slotted waveguide array antenna rotates at 24 RPM and is built to resist wind speeds up to 100 knots (51.5 m/s). Plus, the horizontal beam width of 1.9° ensures precise target detection.
Built for Tough Marine Environments
The display unit operates in temperatures between -10°C to +50°C, while the antenna functions smoothly from -25°C to +70°C. It handles 93% humidity at 40°C and is housed in a rugged, waterproof die-cast body.
