Thales dévoile un radar de surveillance aérienne aux capacités de traitement cinq fois plus élevées

Thales a dévoilé un nouveau radar aux performances significativement accrues par rapport à celles affichées par ses précédents modèles de la gamme GM400. Le radar Ground Master 400 Alpha dispose d'une puissance de traitement cinq fois plus élevée et d'algorithmes d'intelligence artificielles « avancés ». Radar 3D à longue portée, le GM400 Alpha pourra constituer pour les forces armées un « outil précieux pour obtenir un avantage tactique, en détectant tous les types de menaces de manière précoce, offrant ainsi de précieuses minutes pour la prise de décision et l'action », assure l'industriel. Le fonctionnement de ce GM400 Alpha repose sur la technologie numérique à faisceaux superposés, ce qui lui permet de détecter des cibles « allant des jets et missiles rapides aux hélicoptères et drones en vol stationnaire ». Surtout, Thales insiste sur sa capacité à détecter et à poursuive la menace des « drones tactiques volant près du sol », tout en faisant de même, simultanément, pour les chasseurs-bombardiers évoluant à plus haute altitude.

    Pentagon Seeks New SatCom Tech For ‘Fully Networked C3’

    "Our fully networked C3 [Command, Control, & Communications] will look completely different" from current satellites and terminals, said OSD's Doug Schroeder. By THERESA HITCHENS SATELLITE 2020: The Pentagon wants industry ideas on how to craft a “fundamentally new architecture” for command, control and communications (C3) that will allow “any user using any terminal to connect to any other user using any other terminal,” says Doug Schroeder, who oversees the effort under the Office of Research and Engineering (R&E). This kind of omnipresent, all-service connectivity across land, sea, air, and space is essential for the Pentagon's rapidly evolving of future war, known as Joint-All Domain Operations. “Our Fully Networked C3 communications will look completely different. We have a new vision. We're crafting it with the help of industry,” he said. “We're relying on very heavily on industry, starting with this Broad Agency Announcement dated March 6,” which asks for companies to submit white papers in short order. According to Schroeder, the Space Development Agency (SDA) will be the funding authority. Vendors whose short, 10 to 15 page white papers are chosen will be invited at the end of April to a Pitch Day. Winners then will be given three months to develop a proposal; contracts for prototypes will be granted 24 months later. Speaking to a relatively sparse audience here at the annual commercial satellite industry conference, Satellite 2020 — which is underway despite the threat of the COVID-19 Coronavirus — Schroeder stressed: “We are going to take our new direction from you.” The new strategy, called Fully Networked C3 (FNC3), is being spearheaded by R&E director Mike Griffin and his assistant director for FNC3, Michael Zatman. According to the BAA, the first issued under the effort, the new strategy is being designed to “enable the DoD to reliably communicate with all its tactical and strategic assets.” C3 is one of Griffin's Top Ten areas of technology innovation for which DoD is developing an agency-wide development strategy. Specifically, DoD now is looking for “Beyond-Line-Of-Site (BLOS) communications systems for airborne, surface, and subsurface systems that is [sic] compatible with both FNC3 enabled systems and legacy systems,” the BAA states. The BAA calls for White Papers to be submitted by March 30 for three different types of BLOS technologies: 1. Protected Radio Frequency (RF) BLOS Communications. 2. Multi-User/Multi-Point High-Data-Rate Laser Communications. 3. Communications with submerged assets. R&E intends to “develop, prototype, and demonstrate each innovative communications capability with the goal of transitioning the technologies into programs of record,” the BAA said. To ensure speedy results, DoD will use Other Transaction Authority (OTA) for prototyping (found under 10 U.S. Code § 2371b.) Much of the detail about the effort is contained in classified annexes. What we do know: Beyond-Line-Of-Sight communications relayed through satellites generally require equipping platforms — such as aircraft, ships, and ground vehicles — with high-throughput voice and data links, capabilities all of the services have expressed interest in. In particular, after years of little progress, Griffin has reinvigorated DoD interest in optical communications via laser links, in large part due to fears about Russian and Chinese RF jamming. Commercial industry has been rushing to develop optical links to enable satellite-to-satellite data transmission, and the Space Development Agency is interested in that capability for its so-called transport layer of small satellites in Low Earth Orbit. Radio-frequency communications with submarines when underwater are generally limited to terse text messages, transmitted at very low frequencies (three to 30 kilohertz) and extremely low frequencies (three to 300 hertz) and requiring very large antennas to receie them. Research work is ongoing at MIT on how to link traditional underwater sonar to airborne RF receivers, a methodology called Translational Acoustic-RF) communication. Research also is ongoing, including at MIT's Lincoln Lab, on using narrow-beam lasers to allow one underwater vehicle to communicate with another. BLOS communications can also be accomplished without using satellites. Alternative method include tropospheric scatter using microwave radiation, high frequency (HF) wireless, unmanned aerial vehicle (UAV) relays, and passive reflector systems. https://breakingdefense.com/2020/03/pentagon-seeks-new-satcom-tech-for-fully-networked-c3

    Integration is the next step for Air Force information warfare leaders

    Mark Pomerleau Following a significant merger and reorganization of its intelligence, surveillance and reconnaissance and cyber enterprises, Air Force leaders are turning their attention to how these functions can work more closely together. “We're maturing this organization, moving past merging and focusing on integration,” Lt. Gen. Mary O'Brien, deputy chief of staff for intelligence, surveillance, reconnaissance and cyber effects operations, said during a Joint Service Academy Cybersecurity Conference webinar June 11. “We find that our intelligence and cyber roles are focused increasingly interdependent and interconnected.” Within the last 18 months, the Air Force reconfigured its intelligence shop, formerly known as the deputy chief of staff for intelligence, surveillance, reconnaissance, and added cyber effects operations. That change was followed by the merger of two numbered Air Forces – 24th Air Force and 25th Air Force – to create 16th Air Force last fall, the service's first information warfare entity. Officials have said in this new setup the deputy chief of staff handles the workforce, concepts, training, platforms, tools and integration. This is done so operators at 16th Air Force have the guidance they need. O'Brien added that the Air Force is now working at integrating the 2018 ISR flight plan and the 2019 cyber warfare flight plan. Each sought to chart a path for how the Air Force will fight in each respective area into the next decade as part of a great power competition. The ISR flight plan examined transforming the enterprise to meet future threats as opposed to modernization. The cyber flight guided funding, resourcing, training and capabilities for Air Force cyber offices. O'Brien also said integration related to network defense has proven critical with the increased telework during the pandemic. Intelligence and cyber experts are “identifying the threats and they're posturing to defend against them,” she said. "This was not always the case.” https://www.c4isrnet.com/information-warfare/2020/06/11/integration-is-the-next-step-for-air-force-information-warfare-leaders/
