Commercial Marine S-Band Series


SharpEye™ S-Band radar technology meets the challenges of safety, navigation and collision avoidance at sea through a clever combination of radar techniques designed to provide the best performance in all conditions.

Solid state radar ensures extremely high reliability and low through life costs:

  • No magnetron - minimal routine maintenance requirements

  • High reliability - solid state electronics

  • Upmast transceiver solution - no waveguide - easy to retrofit - reduced signal loss

  • Clutter suppression - pulse compression

  • Continuous health monitor


SharpEye™ transmits a low power patented pulse sequence, which enables short, medium and long range radar returns to be detected simultaneously, allowing the radar operator to maintain situational awareness regardless of the range scale setting of the radar display and other users of the radar can select their own radar display range scale. The detection performance of SharpEye™ with a low peak transmission power of less than 200W is equivalent to a 30kW magnetron radar.


The radar performance also increases from the transceiver being positioned upmast, thereby minimising signal loss in the waveguide as well as simplifying installation. The high reliability and lack of routine maintenance means the need to subsequently access the SharpEye™ transceiver is almost removed.
