Description: The KRONOS is a 3D, medium-range, multi-mode, C-band radar with a full solid state active phased array antenna intended for shipboard applications (Kronos 3D NV) for corvettes and patrol boats. It is also suitable for land-based (Kronos 3D LND) applications in air defense and surveillance systems. The Kronos 3D radar system was developed by SELEX Sistem Integrati based on the experience gained during EMPAR ship radar system development. This multi-role system can serve as point defense, long-range surveillance, littoral warfare and fire control radars. In 2009 and 2010 this radar system was ordered by the United Arab Emirates (UAE) Navy for its Abu Dhabi and Falaj 2 patrol boats.

With a low false alarm rate, the system is capable of high priority track, low priority and track while scan (TWS) operating modes. The KRONOS 3D is suitable for operations in ECM (Electronic Counter Measures) environments, severe clutter environments, such as open sea (Blue Water) and extreme littorals (Brown Water) scenarios. It can detect advanced anti-ship missiles with 0.1 sqm radar cross section (RCS) cruising at Mach 3 at 7 meters of altitude at ranges of 20-25 kilometers. With a maximum elevation of 70-degree it can detect targets at ranges of up to 180 kilometers with up to 300 3D tracks with tracking refresh time of 1 second for high priority tracks or 4 seconds for a low track.
