EA11570 D-CASS Deployable Compact Air Surveillance Sensor

The EA11570 is Easat's Tactical Deployable Air Surveillance Antenna. It can be supplied either trailer mounted or palletized. The antenna system is self-contained and capable of being transported by ship, airplane, helicopter or towed to site. The design provides for rapid deployment in less than 45 minutes from arrival at the operating location.

The antenna is a dual frequency band, carbon fibre composite based reflector which operates at S-band (2.7-2.9 GHz) and L-band (1.0-1.1 GHz). Three states of polarization (linear, horizontal, left-hand circular and righthand circular) are provided for S-band beam by use of polarisation-switching capability.

At L-band, the antenna operates in IFF/SSR by use of three beams: sum, difference and omni.

The L-band beacon feed is contained within a common feed/polarizer housing.

A side lobe suppression antenna is provided to illuminate the sidelobe suppression beam.

These features combine to provide leading edge RF performance from the antenna system.
