The contract is for the company's SharpEye radar and MantaDigital Display.
The SharpEye radar system comes in both I and E/F band frequencies. Unlike marine navigation technology now in use, it has no magnetron. Instead it uses a coherent transmission, making it capable of separating small targets from clutter due to their differing radial velocity components, the company said.
The MantaDigital workstation is a multi-function display and hosts radar, ECDIS and conning functionality on a wide-screen.
"We're delighted to be working with the Irish Naval Service with whom we have had a long association," said Rohan Dearlove, Kelvin Hughes' head of Sales, Central Region. "The enhanced performance of SharpEye will undoubtedly enable the service's vessels to operate more effectively."
Kelvin Hughes said the upgrade of the Irish Naval Service's ships will take place over a three-year period. The value of the contract, however, was not disclosed.
