Nautisat S-Band A.T.C. radar antenna system is a modern off-set antenna that benefits of the most advanced techniques and software in the design.
Nautisat S-Band A.T.C. radar antenna system is a modern off-set antenna that benefits of the most advanced techniques and software in the design. The profile reflector and the feed/polarizer system are designed with a Nautisat proprietary software.
The reflector off-set profile is most innovative and it can generate side lobes of very low level. The reflector is equipped with tilting mechanism with graduated scale.
The pedestal with two drive motors is designed to support the primary antenna and a large open array antenna for the secondary radar.
An RF six channels rotary joint and multi-channel slip ring permit the signal flowing the moving parts and the fixed parts.
An encoder box codify the azimuth position.
The antenna structure and surface are made in aluminum alloy.
The pedestal is made in welded and galvanized steel with polyurethane paint.
Nautisat ensure high repeatability in production and high performance and reliability.
