SEADAR-F4 Fixed Digital AESA Faces, 4D, S Band MFR
Introduction to SEADAR-F
SEADAR-F is the most compact version of the SEADAR 4D Multifunction Radars family, all based on 4 fixed faces of advanced Digital AESA antennas. SEADAR-F is a 4D (i.e. 4 Dimensions) radar, since, beside the range and the azimuth, it is able to measure instantaneously also the elevation and the speed of the detected targets. SEADAR-F works in S Band, the best frequency band for Search Radars.
Each digital AESA Face (Digital Antenna Unit; DAU) is composed of 4 standard Virtualabs modules, called VBR. A VBR is a digital AESA “tiles” composed, in turn, of 16 transmitting-receiving elements. The digital VBRs utilize Gallium Nitrate technology (GaN) to generate the RF radiated power.

500 TWS tracking channel (programmable)
Very high data rate (2 sec)
Very accurate Single Target Tracking (suitable for artillery guidance)
Proprietary Anti-nodding function for low altitude targets tracking
Beams for S Band anti-air missile Up-link
Advanced ECCMs
Graceful degradation
Enormous growth potential by only FW/SW upgrading
Digital Array Face dimension: 1.5m x 1.5m
Low weigh (about 600 Kg above deck) and low power consumption.
Modularity
SEADAR can be provided with Digital AESA faces composed of different number of bricks, achieving so, not only advanced 3D Search and Track MFR adequate for installation on small or big ships, but also radars for different applications (e.g. 64 VBRs face for Long Range Detection).
Operational Availability
The solid-state digital arrays that utilize digital TX-RX modules and all digital processing allows SEADAR to get an MTBCF of more than 3000 hours. This means that beside the very high availability a very simplified low-cost logistic support will be required.
