Sensor Data Fusion Offers Countermeasures Against Small Drones


Reading time ( words)

Airbus Defence and Space has developed a counter-UAV system which detects illicit intrusions of unmanned aerial vehicles (UAVs) over critical areas at long ranges and offers electronic countermeasures minimizing the risk of collateral damage.

“All over the world, incidents with universally available small drones have revealed a security gap with regards to critical installations such as military barracks, airports or nuclear plants,” says Thomas Müller, head of the Electronics business line at Airbus Defence and Space. “As a specialist in defence electronics, we have all the technologies in our portfolio and the integration knowledge which are needed  to set up a quick-response protection system with extremely low false alarm rates.”

The system offers very high effectiveness by combining sensor data from different sources with latest data fusion, signal analysis and jamming technologies. It uses operational radars, infrared cameras and direction finders from Airbus Defence and Space’s portfolio to identify the drone and assess its threat potential at ranges between 5 and 10 Kilometers. Based on an extensive threat library and realtime analysis of control signals a jammer then interrupts the link between drone and pilot and/or its navigation.

Due to the Smart Responsive Jamming Technology developed by Airbus Defence and Space, the jamming signals are blocking only the relevant frequencies used to operate the drone while other frequencies in the vicinity remain operational. Since the jamming technology contains versatile receiving and transmitting capabilities, more sophisticated measures like remote control classification and GPS spoofing can be utilized as well. This allows effective and specific jamming and also a controlled takeover of the UAV.

The Counter-UAV System has been tested extensively at Airbus Defence and Space’s own premises and during customer presentations in Germany and France. Depending on the required configuration, an operational system would be available from mid-2016.

Building on recent breakthroughs in autonomous cyber systems and formal methods, DARPA today announced a new research program called Assured Autonomy that aims to advance the ways computing systems can learn and evolve to better manage variations in the environment and enhance the predictability of autonomous systems like driverless vehicles and unmanned aerial vehicles (UAVs).

Beyond Scaling: An Electronics Resurgence Initiative

06/05/2017 | DARPA
The Department of Defense’s proposed FY 2018 budget includes a $75 million allocation for DARPA in support of a new, public-private “electronics resurgence” initiative. The initiative seeks to undergird a new era of electronics in which advances in performance will be catalyzed not just by continued component miniaturization but also by radically new microsystem materials, designs, and architectures.
