Kelvin Hughes


Surface Navy Association National Symposium

Kelvin Hughes is attending the 28th National Symposium of the Surface Navy Association (SNA) which is being held at the Hyatt Regency Crystal City, Arlington, Virginia from the 12th to 14th January.

This is an event that represents an excellent opportunity for us to promote the many benefits of our SharpEye™ technology - superior detection performance and versatility, extremely high reliability and low through life costs. SharpEye™ solid-state radar systems are currently in operation with 25 of the world’s navies from corvettes to offshore patrol vessels and landing helicopter docks.

SharpEye™ transmits a coherent and relatively low power, patented pulse sequence and the use of coherent transmissions enables Doppler processing on the returns to provide an additional dimension for analysis. This in turn enables the detection of very small targets that would be invisible to traditional navigation radar, especially in heavy clutter conditions. Furthermore, the transmitted waveforms can be adapted to enhance returns from specific threats or targets. For example, one popular variant is used for helicopter control and negates the need for helicopters to be fitted with a transponder.

Recently awarded IMO Type Approval, the naval variant comprises the latest Kelvin Hughes SharpEye™ GaN radar transceiver and antenna as well as the world’s first carbon composite upmast housing. The use of the latest GaN transistors has further improved detection performance by increasing peak power over earlier variants and with an upmast transceiver, there is no waveguide to compromise citadel integrity and signal loss is reduced. Moreover, the absence of a magnetron in the transceiver removes the requirement for routine maintenance. With a Mean Time Between Failure (MTBF) for the transceiver of 150,000 hours and a much simplified repair process, the level of maintainer training required is reduced significantly.

The SNA was incorporated in 1985 to promote greater coordination and communication among those in the military, business and academic communities who share a common interest in the activities of surface naval forces. The theme of this year’s symposium is: The Surface Warfare Strategy: A View Beyond the Horizon.
