Easat has recently introduced a printed linear array range of antennas for coastal surveillance and VTS applications. Operating in marine and port X-band frequencies, the antenna uses techniques developed from cellular radio technology together with RF performance, compact size and low weight.<$>The antenna provides azimuth resolution of about 0.31º, whilst transmitting both long and short pulses. The short pulse capability of<40ns enables excellent resolution on very short range targets.<$>The EA7401 antenna offers inverse cosec/ elevation beam shaping, thereby enabling both long and short range targets to be detected from the horizon to -40º below the horizon.
