LIROD MK2 Description
LIROD MK2 is a flexible and compact sensor system, most suitable as an accurate, low cost, all-weather tracker for fire control systems.
LIROD MK2 Details
The system has been designed for as the primary gun control system onboard of smaller ships, against both surface and air targets, and as a secondary system in larger configurations. With an appropriate gun, it is suitable for CIWS functions. LIROD Mk2 is also capable of controlling short-range missiles.
The radar system operates in the K-band, and applies a new, powerful TWT transmitter to improve the performance under adverse conditions. The antenna is of an ellipsoid design to achieve the best low elevation performance against sea-skimming targets, while maintaining fast target acquisition against manoeuvring targets.
