ROME — Radar engineers on the Tempest fighter program have said they expect to break data-processing records. The secret, they explain, is all about miniaturization and going digital.
The sixth-generation jet — planned by the U.K., Sweden and Italy and set to enter service after 2030 — will bristle with new technology, from its weaponry and propulsion to a virtual cockpit projected inside the pilot's helmet.
But the group set the bar high in October by announcing the fighter's radar would process a quantity of data equivalent to nine hours of high-definition video — or the internet traffic of a medium-sized city — every second.
Few details were given to back up the claim, but now U.K.-based engineers with Italian firm Leonardo, who are working on the radar, have shared clues with Defense News.
Boosting performance will mean rethinking today's electronically scanned radars, which have grids of small Transmit Receive Modules, or TRM, on the antenna, each generating an individual radar beam which can follow different targets or combine with others to create a larger beam.
The TRMs in the array are formed into groups, and the signals received by each group are fed to a receiver which digitalizes the data before passing it to the radar's processor.
Due to their size, the receivers must be positioned back from the aircraft's nose and accept the incoming analogue radar signal down coaxial cables, which incurs some data loss before the signal is digitalized.
To remedy that, Leonardo is working on miniaturizing the receivers so they can be moved up into the nose and integrated within the antenna, cutting out the need for a coaxial cable. The data emerging from the receiver must still travel to the processor, but by now it is digital and can flow down fiber-optic cables, reducing data loss.
“Miniaturized receivers can digitalize the signal within the antenna much earlier in the receive chain,” said chief engineer Tim Bungey.
That's one step up from the new state-of-the-art European Common Radar System Mark 2 radar that BAE Systems and Leonardo have signed to deliver for RAF Eurofighters, which will use coaxial cables.
“Digitalizing the data closer to the array means more data can be received and transmitted, the data can be more flexibly manipulated, and there is more potential for using the radar as a multi-function sensor such as for data linking and for electronic warfare,” said Bungey.
There is also a second advantage to miniaturized receivers: Many more can be installed, meaning each one handles fewer TRMs.
“To improve performance and flexibility within the system, a key challenge is to divide the TRMs into more groups containing fewer TRMs, handled by more receivers,” said Bungey.
“By achieving that, together with supporting wider bandwidths, you can generate significantly more data, giving greater flexibility for beam steering and multi-function operation,” he added.
“We are aiming to increase the number of groups of TRMs, and therefore the number of receivers, beyond what will be offered by the MK2 radar for Eurofighter,” he added.
While the radar may push the envelope, Duncan McCrory, Leonardo's Tempest chief engineer, said it would be a mistake to consider it as a stand-alone component.
“The MRFS will be integrated within the wider Tempest Mission System, which incorporates a full suite of electronic-warfare and defensive-aids capabilities, EO/IR targeting and situational awareness systems, and a comprehensive communications system.” he said.
“The data captured by these systems will be fused to create a rich situational awareness picture for the aircrew,” he added.
“This information will also be fused with data received from other aircraft and unmanned systems, with machine learning used to combine and process the overall situational awareness picture for the aircrew. This avoids information overload in the cockpit, enabling the aircrew to quickly absorb data and make decisions based on suitably processed and validated information, and rapidly respond to threats in highly contested environments,” he said.
McCrory added that Leonardo demonstrated aspects of human-machine teaming recently in a trial organized with the British Army and the MoD's Defence Science and Technology Laboratory, in which a Wildcat helicopter crew tasked a semi-autonomous UAV provided by Callen-Lenz to gather imagery and feed it back to the cockpit display via datalink.
“It is these human-machine teaming principles that we will be building upon for Tempest,” he said.

“It is these human-machine teaming principles that we will be building upon for Tempest,” he said.
As Tempest development proceeds, McCrory said design of the integrated mission system was proceeding in parallel with the design of the aircraft itself.
“We are effectively designing the aircraft from the inside out; by this I mean we are working closely with the MoD to understand future sensing, communications and effects capability requirements, and then working with the Team Tempest partners to ensure the aircraft can accommodate and support the required avionic systems.”
Leonardo is working with BAE Systems to ensure the airframe will accommodate sensors, with Rolls Royce to ensure there is sufficient powering and cooling for the systems, and with MBDA, said McCrory, “to give weapons the best available data prior to launch, and to keep them informed after they are released and receive data back from them as they progress towards the target.”

By: Nathan Strout Officials at the newly re-established U.S. Space Command are structuring the organization to take better advantage of commercial space innovations, said Maj. Gen. Stephen Whiting, one of the command's leaders. The Combined Force Space Component Command, which plans space operations, has been working on creating so called “combat development divisions” to seek out and integrate new commercial technologies. Two weeks ago, U.S. Space Command dedicated a full-time position at its Combined Space Operations Center to foster greater cooperation between the military and commercial businesses on space operations. The move is necessary because the reality facing the Department of Defense is that funding for space ventures is increasingly taking place in the private sector, Whiting said. In response to this shift, military space leaders have been tasked with increasing information sharing and collaboration with commercial space operators. That effort started with the establishment of a commercial integration cell, a special group within the Combined Space Operations Center focused on maintaining strong interaction with commercial satellite owner/operators who provide services to the military. Inspired by the success of the cell, U.S. Space Command established a full-time position that will work with companies to make follow-on agreements, codify procedures and explore creating additional CIC-like groups to encompass other areas of space operations such as space situational awareness. Whiting serves as the head of the Combined Force Space Component Command and as the deputy commander of Air Force Space Command and spoke at the Mitchell Space Breakfast Series Nov. 15. U.S. Space Command has also had to adapt to new acquisition models designed to harness commercial innovation, Whiting said. The command is working to form small teams focused on scouting for new technologies, based on the Combat Development Divisions pioneered by Special Operations Command. Brig. Gen. Wolf Davidson, who is Whiting's No. 2 and the head of 14th Air Force, is leading the effort to adapt those models to space operations. These efforts are already bearing fruit. The Combat Development Divisions have helped stand up the DoD's first development platform for building and hosting cloud-native military software applications. The Combat Development Divisions have also been working with the Space and Missile Systems Center and the Air Force Research Laboratory to conduct the Air Force Space Pitch Days, an attempt to bring venture capital-style funding to space acquisitions. “I believe they will not only improve CFSCC's ability to innovate, they will also help our enterprise navigate through the uncertainty and technology disruption of the entrepreneurial space race, bringing down costs, schedule and performance risk to our enterprise along the way,” Whiting said. “We consider this to be a critical task and priority for U.S. Space Command and I think it will continue to be a strategic imperative for our future." These changes are fueled by a shift in space innovation from the government sector to the private sector, explained Whiting. “Since the launch of Sputnik up until the beginning of the last decade, research and development for space technology was almost exclusively funded by nation-states,” said Whiting. "This pattern was not only true for the United States, but for foreign nations as well. But in the past 10 years alone, the number of space companies receiving private, non-government funding has grown from 24 to more than 375.” That's an increase of 1,500 percent in privately funded space organizations, and Whiting said that trend would continue. That means that unlike in the past, innovation for space technologies will happen more in the commercial sector than within the government. “This explosion of innovation also means the calm, predictable environment we enjoyed after the Cold War is decisively over. We have entered a new space race ― an entrepreneurial space race ― and it will pull our enterprise out of its predictable and comfortable state into one that's ambiguous, complex and highly unpredictable," Whiting said. In order to harness that innovation, the military needs to be more open, responsive and collaborative with commercial companies. “It's not going to be enough for countries to outpace each other with exclusively state-sponsored campaigns anymore. Instead, nations will gain the upper hand by harvesting the emergent capabilities of their commercial industry, by unlocking the asymmetric advantage of commercial space operations seamlessly integrated with military space operations. Nations that do not do this run the risk of being left behind, of not being able to capitalize on their indigenous talent," said Whiting. https://www.c4isrnet.com/battlefield-tech/space/2019/11/15/an-entrepreneurial-space-race-could-benefit-space-command/

Bringing together an estimated 33,000 soldiers and civilians from around the world was just too dangerous in the coronavirus era. By SYDNEY J. FREEDBERG JR.on July 21, 2020 at 3:42 PM WASHINGTON: Every October, the Walter E. Washington convention center in downtown DC – a behemoth building covering two whole city blocks – fills with soldiers, contractors, and reporters. Over 30,000 people pack shoulder-to-shoulder in conference rooms to hear from Army leaders, speak face to face, line up for fried chicken, shake hands, hug, and handle military hardware from prototype rifles to full-sized tanks. But with COVID-19 cases rising alarmingly around the country, none of that will happen this October. “We've made the difficult decision to convert the 2020 AUSA Annual Meeting from an in-person meeting to a virtual experience,” said retired Gen. Carter Ham, the Association of the US Army's president and CEO, in a statement Tuesday afternoon. The mega-conference – historically one of the biggest in-person gatherings for the defense industry in the DC area – will now take place entirely online over Oct. 13-16. Breaking Defense plans to cover the virtual event as exhaustively (and as exhaustingly for our reporters) as it has the physical one every year since 2011. “With recent trends, it just became clear to me that we simply could not, in any reasonable manner, ensure a safe, secure environment for the 32,000-plus people we expected this October,” Gen. Ham told me in an follow-up email. “We are working very closely with the Army to craft an agenda which provides opportunities for key leaders to connect with our members and constituents.” “One of the keys to that is finding ways to connect Army leaders with the businesses, large and small, who normally are present in the exhibition hall,” Ham said. “Finding a way to do something similar to that experience in the virtual world will be a challenge, but it is an integral part of the AUSA Annual Meeting, so we'll figure it out.” AUSA is still working out the logistics of this massive switch. Registrations and sponsorship agreements from the in-person version of the event will not automatically carry over. “Registration for the new virtual meeting is expected to open by September,” the AUSA statement says. “AUSA is now coordinating details for the virtual event, and team members will be reaching out directly to exhibitors and sponsors about new opportunities.” With over 600 sponsors in a typical year – ranging from small businesses with a single, small booth to titans like Boeing and Lockheed Martin – the Annual Meeting is a major source of revenue for AUSA. How this will impact the association's budget is unclear – even to AUSA itself at this point. Breaking Defense graphic from AUSA data “The AUSA Annual Meeting is our most important revenue-generating event of the year,” Ham said bluntly. “The revenue from this event is largely what allows us to conduct other events throughout the year. So, I don't know yet precisely what the impact will be, but there will be some effect. Fortunately, AUSA is in a strong financial position so we will be able to sustain this change.” AUSA's latest annual report said the 2018 conference “generated $16 million in revenue,” just under half the association's total projected revenue of $33 million for the 2018-2019 fiscal year. (The report for 2019-2020 hasn't been published yet). But AUSA also reported its investment portfolio was worth $51 million; that was as of May 2019, before COVID roiled the stock market, but the portfolio should still be large enough to offer at least some buffer. The initial wave of the COVID-19 coronavirus forced AUSA to cancel its Global Force conference in Huntsville, Ala. this March just a week ahead of opening day. That gave the association no time to schedule virtual alternatives, although multiple events from Army aircraft announcements to Shark Tank-style pitch meetings were hastily turned into teleconferences or webcasts. Global Force had expected some 6,000 attendees. Since then, AUSA has held a host of online events, largely but by no means entirely without glitches, but they were all much smaller in scale. The Annual Meeting had expected some 33,000 attendees. Moving that conference online will be a vastly larger organizational and technical challenge. It's also an opportunity, Ham argued. “While we will all certainly miss the opportunity to be together with the broader Army Family, choosing to provide our programs in a virtual environment does offer us an opportunity to connect with audiences who might not know AUSA all that well or who have simply not been able to travel to Washington DC for the event in prior years,” he told me. “I view this very much as a chance to extend our reach and to more effectively fulfill our mission to support the Army.” Even if nothing glitches, though, the virtual Annual Meeting won't replace the human connection that came from the Army's annual gathering of its disparate tribes. “What will I miss? This is the Army's family reunion,” Ham said. “Every October, the opportunity to see old friends and to make new friends is the most enjoyable part of the Annual Meeting. I'll miss that, to be sure, but I also know that via this virtual experience, we will make new connections, new relationships that will make AUSA 2021 even better when we can all be together again.” https://breakingdefense.com/2020/07/covid-drives-ausa-mega-conference-online/
