Kelvin Hughes to supply Royal Canadian Navy with downmast submarine radar

Kelvin Hughes, a world leader in maritime navigation and security surveillance radar, is delighted to announce that it will be supplying its SharpEye™ downmast submarine navigation radar in support of the Royal Canadian Navy’s sustainment program.

Kelvin Hughes to supply Royal Canadian Navy with downmast submarine radarTwo of the navy’s Victoria-class long range patrol submarines, currently equipped with Kelvin Hughes 1007 radar, are to be upgraded with the company’s new SharpEye™ system. With solid-state technology at its heart, the I-Band transceiver uses the existing bulkhead infrastructure as well as the external antenna, rotational drive and waveguide connections.

Doppler processing of the radar returns means that surface contacts can be detected earlier and at longer range. A series of electronic filters enables the system to distinguish between contacts of interest, including those with a low Radar Cross Section, and the environmental clutter caused by adverse weather conditions.

Traditionally, submarines have only used radar for navigation in and out of port because high power RF transmissions can compromise its ability to remain undetected. However, with its low power output – up to 300W as opposed to the 25kW of legacy submarine radar equipment - SharpEye™ can significantly reduce the probability of detection by ESM systems.

The Victoria-class submarines, acquired from the Royal Navy in the 1990s, can operate in the Arctic, Pacific and Atlantic approaches to Canada and have the flexibility to undertake a wide range of missions, significantly extending the Royal Canadian Navy’s tactical and strategic capabilities.

Adrian Pilbeam, Kelvin Hughes’ Vice President Kelvin Hughes LLC, commented:

“This upgrade for the Royal Canadian Navy is a further example of the growing interest in our SharpEye™ downmast submarine variant and highlights the need for submarines to be equipped with modern high performance radar rather than the legacy magnetron systems that many of them are still using.”



Kelvin Hughes Ltd is a world leader in the development, manufacture and supply of maritime navigation, surveillance and security radar systems. The company sets the international standard in solid-state radar sensor technology with SharpEye™ and its market leading tactical and situational awareness radar display software. w:
