Support for Aveillant

Holographic Radar Trial Support - Helios was contracted by Aveillant to conduct an independent review, quantitative analysis and report of the performance of their Holographic Radar at Prestwick.

Aveillant

Context

The installation of wind farms close to radars used to provide Air Traffic Control impact the performance of these radars, and in particular Primary Surveillance Radars (PSR). Due to the size and the velocity of the rotating turbine blades the reflections of the transmitted radar pulse look very similar to those from aircraft. The Aveillant Holographic RadarTM has been designed to solve this problem of wind farm interference by filtering out the clutter/false plots generated by the wind farms but still detecting the aircraft over the wind farm. The Holographic Radar solution is currently designed to provide surveillance data in the vicinity of wind farm and to then seamlessly integrate this with the surveillance data from the affected PSR.

Role of Helios

Helios was contracted by Aveillant to conduct an independent review, quantitative analysis and report of the performance of the Holographic Radar at Prestwick. The aim of this analysis was to provide quantitative data to back up the qualitative observations made during the recent trial and demonstration days to aid discussions with other stakeholders.

Results

The results of both the quantitative and qualitative analysis showed that the Aveillant Holographic RadarTM performance meets the likely technical and functional performance requirements for providing a surveillance separation service in the vicinity of a wind farm. It was qualitatively observed that the probability of detection and false plot performance of the Holographic Radar was much greater than that of the GPA PSR in the vicinity of the wind farm. The quantitative analysis also demonstrates that the Holographic Radar performance is much higher than the typical performance of a PSR, and in some cases, more in line with the performance of co-operative surveillance systems.
