Hensoldt radar demos ATC capabilities
Hensoldt has demonstrated the ability of its Twinvis passive radar system to provide air traffic control capabilities, the company announced on 29 July.
During a test campaign a radar sensor cluster was installed at four sites in South Germany - Nuremberg, Roth, Erding and Ulm. The sensors successfully monitored and tracked air traffic in the area in real time, while the data was processed centrally at Hensoldt’s Ulm site.
Working as receivers which don’t emit any radiation, passive radar systems detect aircraft by analysing the signals that they reflect from existing third-party emissions. The Twinvis system provides a comprehensive overview of the airspace covered by simultaneously analysing a large number of frequency bands, including up to 16 FM transmitters (analogue radio), five frequencies used by several DAB and DAB+ transmitters (digital radio) and DVB-T and DVB-T2 (digital, terrestrial television).
In military applications, the system enables wide-area surveillance using networked receivers, while offering the advantage that passive radar systems cannot be located by the enemy and are very hard to jam.
As the radar emits no radiation, no agreement is required with any other public authority, enabling the system to be quickly ready for deployment in new locations, including urban areas.
