Paris 2024: “Hard death”, blocking rifles and net capture to neutralize unwanted drones

Irruption of a swarm of drones carrying an explosive charge or unleashing a formal cyber attack against the headquarters of the Villacoublay air base (Yvelines) that will monitor the skies over Paris: as the opening of the Olympic festivities approaches, the The Air Force has listed eighteen Scenarios that the fifteen complete anti-drone systems installed in Paris and Marseille could face. Thanks to the deployment of this sophisticated equipment, the sensitive venues that will host the Olympic and Paralympic Games (JOP) this summer will be able to immerse themselves in a “bubble” capable of repelling any intrusion.

How can we protect a large-scale event like JOP from the threat of malicious drones? The answer is both simple and complex. Security forces may rely primarily on “heavy devices” installed at a specific location. An unmanned aircraft can be detected by radio direction finding (to determine which direction it is heading), from its electronic fingerprint captured by equipment well known to the military, or even through the use of highly advanced radars.

However, nothing is more difficult than achieving secure and immediate identification of a machine several kilometers away. At this distance, the radar signature of a small quadcopter can easily be mistaken for that of a bird, despite the use of artificial intelligence. However, if it is not immediately identified as a police or accredited media drone, the suspect aircraft will be subject to magnetic jamming.

Great means of last resort.

These solutions are less effective when the plane is in regular flight, because then there is no link with a remote pilot that allows you to return to it. Certain precautions must also be observed, because disrupting a drone’s GPS signal without being very precise risks affecting other nearby users, such as “friendly” drones, the police or emergency services.

If the plane manages to get close, it will face what industrialists and the military modestly call “effectors”, that is, weapons that allow immediate neutralization. We can mention the anti-drone rifle (the police one weighs 12 kg and costs 17,000 or 30,000 euros each depending on the model) that will “spray” the suspected drone(s) with a more powerful signal than the one received from the pilot. remote. . Depending on how it has been programmed, the target aircraft will hover, land, or return to its base.
