Thales et Airbus vont moderniser les outils de collecte de renseignements électroniques des armées françaises
Les trois armées (air et espace, terre, mer) françaises disposeront bientôt de moyens de collecte de renseignements électroniques unifiés, fournis par Thales et Airbus.
En matière de collecte de renseignements électroniques, les différentes armées françaises disposaient chacune de leurs propres technologies. Ce sera bientôt de l'histoire ancienne. La DGA (Direction générale de l'armement) a chargé fin 2020 Airbus et Thales de lui fournir des capacités de recueil du renseignement d'origine électromagnétique (ROEM) unifiées. Un contrat d'une durée de dix ans, dont le montant total n'a pas été communiqué.
Dans les années à venir, les trois armées (de l'air, de terre et marine nationale) disposeront toutes du même type de capteurs, matériels et logiciels pour capter les communications de leurs adversaires sur les différents thé'tres d'opérations. De quoi améliorer leurs capacités en matière d'écoute, de radiogoniométrie (qui permet de localiser une émission hostile, radar ou radio par exemple) et d'exploitation du spectre électromagnétique, gr'ce à des technologies de dernière génération. Cette unification permettra aussi aux différents corps de mieux se coordonner. La formation des spécialistes en sera, enfin, facilitée. La DGA a passé une première commande fin 2020 pour 160 millions d'euros de matériels et logiciels, qui seront livrés à partir de 2023.
Rester au niveau dans la guerre électronique
Le système interarmées ROEM tactique sera utilisé sur des véhicules Scorpion en remplacement des équipements tactiques actuels, sur les navires de premier rang de la marine nationale et les avions de patrouille maritime Atlantique 2, et pour la protection de bases aériennes. Airbus et Thales fournissaient déjà certaines briques technologiques de l'arsenal déployé par la France dans la guerre électronique. Le second avait développé le programme Cohorte (système actuel de ROEM tactique utilisé par l'armée de terre), le premier le programme Ramses (Evolution du système d'information stratégique traitant des communications radio et satellite).

Spectrum Warfare Wing’s Koslov eyes fast retooling for ‘wicked threats’
“If you think about trying to get data to fighters, to bombers, to weapons, to countermeasures, to all the things that we do, that’s a good number.”

Could soldiers silently communicate using brain signals in the future?
Andrew Eversden WASHINGTON — A breakthrough in decoding brain signals could be the first step toward a future where soldiers silently communicate during operations. New research funded by the U.S. Army Research Office successfully separated brain signals that influence action or behavior from signals that do not. Using an algorithm and complex mathematics, the team was able to identify which brain signals were directing motion, or behavior-relevant signals, and then remove those signals from the other brain signals — behavior-irrelevant ones. “Here we're not only measuring signals, but we're interpreting them,” said Hamid Krim, a program manager for the Army Research Office. The service wants to get to the point where the machine can provide feedback to soldier's brains to allow them to take corrective action before something takes place, a capability that could protect the health of a war fighter. Krim pointed to stress and fatigue signals that the brain gives out before someone actually realizes they are stressed or tired, thus letting troops know when they should take a break. The only limit to the possibilities is the imagination, he said. Another potential future use is silent communication, Krim said. Researchers could build on the research to allow the brain and computers to communicate so soldiers can silently talk via a computer in the field. “In a theater, you can have two people talking to each other without ... even whispering a word,” Krim said. “So you and I are out there in the theater and we have to ... talk about something that we're confronting. I basically talked to my computer — your computer can be in your pocket, it can be your mobile phone or whatever — and that computer talks to ... your teammate's computer. And then his or her computer is going to talk to your teammate.” In the experiment, the researchers monitored the brain signals from a monkey reaching for a ball over and over again in order to separate brain signals. But more work is to be done, as any sort of battle-ready machine-human interface using brain signals is likely decades away, Krim said. What's next? Researchers will now try to identify other signals outside of motion signals. “You can read anything you want; doesn't mean that you understand it,” Krim said. “The next step after that is to be able to understand it. The next step after that is to break it down into into words so that ... you can synthesize in a sense, like you learn your vocabulary and your alphabet, then you are able to compose. “At the end of the day, that is the original intent mainly: to have the computer actually being in a full duplex communication mode with the brain.” The Army Research Office-backed program was led by researchers at the University of Southern California, with additional U.S. partners at the University of California, Los Angeles; the University of California, Berkeley; Duke University; and New York University. The program also involved several universities in the United Kingdom, including Essex, Oxford and Imperial College. The Army is providing up to $6.25 million in funding over five years. https://www.c4isrnet.com/battlefield-tech/it-networks/2020/11/25/could-soldiers-silently-communicate-using-brain-signals-in-the-future/
