Situational Intelligence, The World Over


SharpEye™ SCV Small Boat Radar

Kelvin Hughes will be showing the SharpEye™ SCV (Small Craft Variant) and specialist display technology at the DSEI (Stand Number S4-110) exhibition in September.

Kelvin Hughes will be demonstrating SharpEye™ SCV with a specialist display from SeaCross Marine AB.

Until now, maritime law enforcement, military and naval users, have had to use leisure boat radars in the absence of a professional radar alternative.

Russell Gould, Chief Executive of Kelvin Hughes, said:
“The SCV small boat radar is a very special piece of equipment. Incorporating many of the elements of the SharpEye™ system used on naval platforms. The all-weather radome X-Band radar will, for the first time, bring professional radar performance to the smaller vessel and significantly increase the capability of police and patrol boats, which often need to detect small targets at greater ranges or in adverse weather conditions.”

Kelvin Hughes is seeing a lot of interest in the radome radar, with requests for trial and test opportunities from all over the world, as the industry starts to catch on to this new technology. Its unique features set it apart from every radar that has come before it, with its lightweight, high-performance and durable design.

Kelvin Hughes will also be showing the SeaCross Marine display option for SCV at this year’s DSEI. The display was designed with special forces in mind and when combined with SCV, provides the optimum solution for those vessels requiring more from their radar.

Harald Nilsonne, Managing Director of SeaCross, said:
“Not only can our combined offering give small boat users improved situational awareness; it also addresses some of the more specific issues of operation – such as using a navigation system at high speed in the dark. The combination of Kelvin Hughes’ SharpEye™ radar and SeaCross’ display software is giving small craft a much higher level of navigation capability.”

SharpEye™ SCV

The SharpEye™ SCV radome is designed for easy installation on radar arches and masts. It has a flexible interface making it possible for the core high performance element of the radar system, the transceiver, to interface with other radar displays. The company offers a SeaCross Marine 15” or 12” fully waterproof and ruggedised console display with a state-of-the-art solid state ruggedised processor.

SharpEye™ SCV provides a robust and reliable solution to improve situational awareness for small watercraft, enabling autonomous vessel operation with informed real-time and local tactical decision making.

A key feature of the technology is the use of pulse compression and Doppler processing to provide superior target detection. The solid state electronics design requires no routine maintenance and, unlike most small boat radars, has no components that degrade with time i.e. a magnetron – so high performance is maintained throughout the long life of the unit.

Another advantage of the SharpEye™ technology is the low peak power of the transmission – up to 80W –compared to anything up to 10kW from an equivalent magnetron radar. This low power, coupled with a precise use of frequency, makes it very difficult for ESM equipment to detect the transmission. The user can also select individual transmit frequencies, power modes and configure azimuth sector blanking to further improve the covert characteristics of the device.

Key Features:

  • Resistant to jamming
  • Resistant to interference
  • Doppler processing
  • Fully integrated transceiver, power supply and GPS into the radome
  • No magnetron
  • Power amplifier dual redundancy
  • Concurrent long and short range transmissions
  • X-Band / I-Band

Kelvin Hughes and SeaCross

Kelvin Hughes is working with SeaCross Marine AB – another navigation specialist – to provide further surveillance solutions for small boats. The SharpEye™ radar is able to detect the smallest of targets in clutter; targets moving at speed that could be described as agile; and asymmetric threats.

SeaCross has developed a customisable display specially designed for high-speed navigation in littoral and coastal waters. The display and software solution for small boats has numerous special features, notably night vision operation, which allows the user to engage the system in dark conditions.

Key Features:

  • User customisation with a ‘save display’ setup, which develops with use.
  • SeaCross incorporates a unique set of radar functions and displays that makes radar image understanding and interpretation easy for the less experienced radar user.
  • The system is an open architecture setup designed to interface with sensors, utilising a wide range of protocols and standards, and taking inputs such as depth from other sensors around the boat.
  • Customisable colour and contract settings for different conditions and light environments.
  • Night vision mode for operating the system in the dark.


  • RHIB
  • Patrol boat
  • Life boat
  • Hover craft
  • Police boats
  • Search and rescue
  • Military boat
  • Fast attack craft
  • Landing craft

Kelvin Hughes is now looking forward to showing the new display system for the SharpEye™ SCV radar at DSEI from 10th-13th September.
