Aveillant radar goes long-range

Cambridge University spin-out Aveillant has launched a long-range version of its high-precision 3D surveillance radar technology.

The company’s patented “holographic radar” will be demonstrated as a full-sweep system, covering 360 degrees of airspace at a range of over 40 nautical miles, in the third quarter at an unnamed offshore wind farm.

The next generation system, an evolution of the technology trialled at Glasgow Prestwick airport last year, will use a multi-faceted array configuration to provide continuous three-dimensional coverage of airspace.

A high update rate – twice per second – provides improved precision to controllers and “easy integration” into the latest surveillance systems such as Wide Area Multilateration (WAM) and Automatic Dependent Surveillance Broadcast.

“Our technology now provides a full primary surveillance radar capability which gives us huge potential to expand. We will continue to extend our range to offer holographic radar solutions that go beyond wind farm mitigation and open up many exciting new application areas such as force protection, border security and maritime surveillance,” says Aveillant commercial director John Allan.

Unlike conventional radar technology, non-rotating holographic systems use a static staring array to continuously track radar targets and to capture their unique Doppler signature.

The Aveillant system is said to have 100% “time on target” which makes it possible for each target to be intelligently characterised and identified based on this signature, while traditional rotating radars typically spend less than 1% “time on target” and so cannot feed back the same detail of information.
