Lockheed Martin has selected Kelvin Hughes’ SharpEye radars to be fitted to more than 60 UK Royal Navy (RN) and Royal Fleet Auxiliary (RFA) ships, submarines and shore facilities.

The selection of Kelvin Hughes for supply of its radars is part of a £44m contract secured by Lockheed Martin with the UK Ministry of Defence (MOD).

The Royal Navy’s Type 23 frigates, Hunt and Sandown class Mine Counter Measure Vessels, RFA support vessels and fast patrol boats, as well as the Astute, Trafalgar and Vanguard class submarines, will be fitted with Kelvin Hughes’ SharpEye radar.

“SharpEye can differentiate between targets of interest and clutter, while customisable waveforms can be configured for specific threats.”

Additionally, five shore facilities will be benefitted from the SharpEye technology, including HMS Collingwood in Hampshire, HMS Raleigh in Cornwall, and the Land Based Test Site at Portsdown Technology Park in Hampshire.

Available in both I (X) and E/F (S) frequency bands, these have a component commonality due to their similar modular design and system architecture.

As the technology can be offered on both frequency bands, the MOD can save on expenditure in training, documentation and support.

The SharpEye solid-state radar transceiver emits a low power, patented pulse sequence incorporating pulse compression, which allows superior range discrimination across all range scales. This implies that several operators can have access to an optimum picture at both long and short ranges simultaneously.

Doppler processing of radar returns offers information regarding a target’s velocity and improves the probability of detection of small objects with a low radar cross section.

SharpEye, through a series of electronic filters, can differentiate between targets of interest and clutter, while customisable waveforms can be configured for specific threats, enhancing the detection of specific targets of interest such as UAVs and helicopters.

Further, the radar’s low power output cuts down the probability of detection by enemy ESM equipment.

Kelvin Hughes chief executive Russell Gould said: "SharpEye systems are currently being deployed by 27 of the world’s navies, and this major new project is a further vote of confidence in the superior performance and reliability of Kelvin Hughes SharpEye™ technology."

In 2013, Kelvin Hughes was selected by the Irish Naval Service to provide SharpEye radar and the MantaDigital display as part of its fleet’s incremental upgrade programme.
