EA45075 Antenna

The EA40575 radar Antenna provides two separate elevation beams, one optimized for air surveillance, the other optimized for sea surveillance.

Remotely controlled polarisation switching is provided between Horizontal (HP) and Circular (CP) on both beams. Polarisation can be individually selected for each beam. The antenna can also accommodate various forms of IFF antennas

The antenna offers sub 0.52° azimuth 3dB beamwidth giving excellent range and azimuth resolution providing excellent target discrimination at long range. Offering a high standard specification, the antenna includes selectable horizontal or circular polarisation for weather penetration on both air and sea beams. On the air beam, the antenna provides inverse cosec2 shaping for constant target illumination, and a modified pencil sea beam for long range detection and reduced rain and sea clutter

The EA45075 antenna is designed for use mounted on a stabilised platform. An Easat turning unit and stabilised platform can be provided, or it can be mounted on a turning unit supplied by the customer.
