Transmit/Receive Module technology and related multifunction active radars in Selex-Sistemi Integrati

The paper deals with the SELEX-SI Transmit/Receive Module (TRM) technology and related radar applications. Since the end of '90s SELEX-SI started its activities on the active technology, establishing a 20 years Road Map including GaAs and GaN components and evolving through the increase of effective generated power and efficiency, and through the decrease of Noise Figure for sensors applications. The Road Map is comprehensive of a large frequency band interval, with specific attention to C and X band. As far as it concerns the G band radar sensor application of the active technology, this paper describes Selex-SI Active EMPAR (in the future named C-HOUND) and KRONOS radars. KRONOS and Active EMPAR are multifunctional, multi-role G-Band radars based on Active Electronically Scanned Antenna (AESA). Active EMPAR is designed as a technologic upgrade of the SELEX Sistemi Integrati well proven EMPAR Multifunctional radar system provided to the Italian and French Navies. In this paper the two radar features will be detailed in terms of implemented technical and technological solutions and related advantages in surveillance, tracking and other functionalities required for a Combat System.
