Aveillant is a UK-based surveillance company that offers a range of groundbreaking products based on its innovative 3D Holographic Radar™ technology. Providing target-centric surveillance, 3D Holographic Radars™ use a flat-panel stationary array that provides huge benefits over traditional rotating radars. This includes an exceptionally high update rate (updating every half second to two seconds), 3D coverage providing real-time coverage of targets in terms of position, elevation and speed, and intelligent characterisation and identification of returns.  These unique capabilities led to the 3D Holographic Radar’s™ first application, as a solution to mitigate the impact of ‘clutter’ caused by wind farms on air traffic control radars. However, clutter on radar pictures can be caused by many things including waves at sea and road vehicles, and the benefits of 3D Holographic Radar™ are gradually becoming realised by marine, defence and airspace industries across the globe. Holographic Radars™ use L-Band frequencies, as opposed to the highly congested S-Band frequencies, also highly sought after by mobile phone operators, used by many air traffic control radars. The UK Government wants to release 500 MHz of public spectrum in the S band by 2020 and has tasked the Civil Aviation Authority (CAA) with finding a solution. The CAA has already awarded Aveillant a contract to demonstrate the use of Holographic Radar™ in support of the Spectrum Release program.
