    NAVAL MULTIFUNCTIONAL ACTIVE RADAR FOR
    PRINCIPAL ANTI-AIR MISSILE SYSTEM

    KRONOS® Grand Naval is multifunctional radar based on KRONOS Grand Naval uses its multifunctional capability to
    advanced Active Electronically Scanned Array (AESA) simultaneously and independently perform surveillance and
    technology, used as main radar for the Principal Anti-Air targets tracking by electronically scanning the beam both in
    Missile System (PAAMS). KRONOS Grand Naval applications azimuth and elevation, in addition to mechanical rotation. The
    include extended self-defence, air and surface surveillance system offers high-performance ECCM features.
    and simultaneous multiple targets tracking, volumetric
    search and multiple missiles guidance. KEY FEATURES
    KRONOS Grand Naval is the main system of the PAAMS.
    THE SOLUTION PAAMS is a 360º omni-directional system providing
    KRONOS Grand Naval is the most advanced 3D naval radar multilayer air defence to surface group warships or groups
    worldwide, demonstrated by a range of trials on board the of unarmed support and merchant ships. It includes three
    FREMM class vessels. Its multifunctional capability enables separate roles in a single naval air defence system: ship

    self-defence and area protection in complex scenarios and long range.
    against multiple attacks in very severe clutter and jammer
    environments. KRONOS Grand Naval is based on the company’s extensive
    experience in the development of multifunctional radar
    Being fully solid-state and with redundancy for all systems. This began more than 20 years ago with the
    equipments, it offers an unrivalled high reliability of the multifunctional radar EMPAR, which was then installed on the
    system. French/Italian Destroyers (Horizon) and Italian Aircraft Carrier
