The use of small unmanned aircraft systems (sUAS) or ‘drones’ is increasing rapidly. This has many positive benefits but also comes with safety and security risks that must be managed. These include UAS collision with manned aircraft, UAS collision with people on the ground and wider security threats such as the protection of personal privacy and terrorist activity. The “Gamekeeper” radar has been...
Ground-to-air surveillance systems typically comprise of scanning radar that provide good Doppler detection over a wide angular sector. However, since such systems tend to have a limited Doppler resolution, their detection performance can be significantly impacted by unwanted Doppler echoes that are co-located with genuine target returns. These issues can be overcome by switching to an entirely fixed...
A major challenge facing non-cooperative Primary Surveillance Radar (PSR) is performance impact as a result of interference due to wind turbines. By using a staring array and advanced signal processing techniques it is possible to reliably distinguish the unwanted turbine returns from the wanted aircraft returns allowing a clear non-cooperative picture to be presented to downstream systems and the...
