The GEM elettronica ASX-2101/S • ASX-1901/S Series constitutes the top in the art of design and production of radar antenna systems. Designed for vessel traffic management, coastal surveillance and security airport traffic monitoring, its unique property of non-dispersion versus the frequency of operation provides zero-squint radiation, a must for wideband, fully solid state systems. Radar pulses are kept un-distorted, so ensuring superb angular discrimination even when connected to non-diverse, magnetron-based radar transceivers to automatically compensate for the magnetron’s frequency shift avoiding unwanted pulse modulation.
The antenna “backlash” is definitely eliminated so that the bearing data is extremely precise.
The ASX-2101S/ASX-1901S Series can be provided with horizontal or circular polarization so making it the choice in many shored-based installations.
- High azimuth discrimination
- Wide band of operation
- Functionality 24 h for 360 day/night all-weather conditions.
- Can be remotely driven to select different rotation rates
- Can interface different GEM elettronica radar transceivers
- Maintenance free (MTBF more that 60000 h)
The antenna system series ASX-2101/S • ASX-1901/S is targeted to top-ranked applications, such as:
- Vessel Traffic System (VTS), Vessel Traffic Management & Information Systems (VTMIS)
- Coastal Surveillance & Security
- Surface Movement Guidance Control System (SMGCS)
- Homeland Security
GEM elettronica offers a complete range of high-gain antennas in both X, S and Ka band designed for naval vessels, coastal/harbour surveillance and Airport Surface Movement and Guidance Control (SMGC) systems.
GEM elettronica has developed different versions of these antennas to satisfy diverse applications. In particular, GEM elettronica’s down-mast antennas provide high-reliability operations in all-weather conditions and are delivered with a complete pedestal inclusive of electro-mechanical drive unit, rotary joints and tilt. Thanks to their superior mechanical design, GEM elettronica’s antennas eliminate the “backlash” problem and deliver an extremely precise bearing data.
