Frequently asked questions:

1. What is 3D Holographic RadarTM? 3D Holographic Radar™ is a new and advanced 'staring array'-based radar that offers a revolutionary advance in tracking and surveillance radar capability. It provides a real-time, three-dimensional surveillance of the airspace through its use of a modular array that can be configured to match the airport requirements of range and coverage. Unlike traditional scanning radars, 3D Holographic Radar™ actually characterises, identifies and intelligently decides what to do with the returns it receives, depending upon the requirement. In the case of wind farm mitigation,...

4. Are there any range limitations? The 3D Holographic Radar™ product is a completely modular solution. Transmit modules are added to increase the transmitter power and receiver modules are added to improve sensitivity and resolution. A single 360-degree installation can mitigate beyond the typical 20nm protection zone around an airport PSR. In addition a 3D Holographic Radar™ can be deployed remotely at a wind farm site and integrated with more than one PSR feed. This is possible because the output from a 3D Holographic Radar™ is three-dimensional and there is no slant range error to account...

8. Why is HR good at differentiating wind turbines from aircraft? 3D Holographic Radar™ is unique in that it does not use any form of 'blanking' or 'range gating' to reduce the effect of wind turbines on the radar. A 2D scanning radar is effectively 'ignoring' the airspace over the turbine (the same effect as blanking) but the smaller the blanking area, the higher the need for RF spectrum. As RF spectrum availability is reducing, this is not a sustainable approach. The operational mode of 3D Holographic Radar™ is quite the opposite of traditional scanning radars in that it wants to see the turbines...

11. Who is Aveillant? Aveillant is a UK technology company, which spun off from Cambridge Consultants in October 2011. It employs radar, technology, air traffic control, mapping and commercial experts to design, deliver and support the 3D Holographic Radar™ technology. The core of the design team has been focused on designing radar technology that focuses on the understanding and characterisation of the radar returns rather than on identifying movement at long range. The 3D Holographic Radar™ technology enables an intelligent picture of the surveillance area to be created and managed. 12. Has...

14. How much does it cost? In the UK, for wind farm mitigation, the 3D Holographic Radar™ is mainly provided as part of a surveillance data service. This is where an airport has agreed that Aveillant will provide a comprehensive service to local wind farm developers on behalf of the airport which includes the provision of 3D Holographic Radar™ units as required to mitigate whatever wind farms are approved for the area and which affect the PSR of the airport. The wind farm developer pays an annual fee for the service which is comparable to the Community Benefit Payment that it is required to make. Aveillant...
