Onwa KR-1068 Marine Radar

Reliable Marine Radar for Safer Navigation

The Onwa KR-1068 Marine Radar is a high-performance radar system built to enhance maritime safety and accuracy. Designed with a 9.7-inch LED backlit color display, it provides clear radar images up to a 64nm range.

Precision with Powerful Antenna

Equipped with a slotted waveguide array antenna, the radar ensures stability even in wind speeds up to 100 knots. With a 24 RPM rotation speed and wide beam coverage (1.9° horizontal, 22° vertical), it detects nearby vessels and obstacles fast and effectively.

Versatile Radar Functions

It operates on the X-band frequency (9410 ± 30 MHz) and uses MAF1422 or MSF1422 transmitting tubes. Its flexible pulse settings adjust performance for short and long-range scanning—ideal for nearshore and offshore navigation. With a 6 kW output, you get a crisp, strong signal.

Smart Display and Tracking

Choose from Head-up, Course-up, or True Motion display modes. Track up to 40 targets with CPA/TCPA alerts. Echo trails offer clear motion tracking. With auto or manual tuning, operation is simple and flexible.

Built to Last

The radar withstands tough conditions with its robust antenna and reliable IC-based receiver. Operating from -25°C to +70°C, it’s ready for any voyage.
