Surface Movement Radar - SMR Linear Array

Easat have designed a range of high-performance, low-cost Linear Array antennas specifically for Ground Movement Radar Control at airports.

The Easat Linear Array antenna EA6501 is targeted at the SMR markets in the USA. The model EA7401M is targeted at the SMR markets in other parts of the world such as Canada, Europe and the Pacific Basin.

The EA6501 has been specified and used by the FAA at 24 of the larger commercial airport sites within the USA. The EA7401M antenna has higher power-handling capacity, suitable for use with magnetron-based transceivers. This antenna has been specified and used by Navcanada exclusively for all 10 major airports in Canada, and is also on many major European airports such as Brussels, Zurich and London Heathrow.

The Linear Array antenna design is based on cellular radio technology and provides high performance at low cost. The X-band Linear Array antenna offers Ku-band type
resolution with a sub 0.34º (demonstrated) beamwidth, and gives excellent range and azimuth resolution superior to that provided with slotted waveguides. The antenna provides operation with 40 ns pulse width without pulse distortion, and zero squint at multiple frequency, making it ideal for use with a magnetron, solid-state, frequency-agile or FMCW system.
