    Secrets of Tempest’s ground-breaking radar revealed

    Tom Kington 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. “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.

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.” https://www.c4isrnet.com/home/2021/01/15/secrets-of-tempests-ground-breaking-radar-revealed/

    Windsor police unveil new crime fighting drone

    TREVOR WILHELM It's a bird. It's a plane. It's the Windsor Police Service. Windsor police officially launched their new drone program Wednesday with a show-and-tell at their Sandwich Street training facility. Before sending one into the sky outside the Major F.A. Tilston Armoury and Police Training Centre, officers stressed they will not be using drones to randomly watch people. “We will not be going out there to do traffic stops,” said Staff Sgt. Sue Garrett, who runs the operational support unit. “We will not be putting it out there for routine policing on a daily routine. It will always have the proper judicial authority in order to use that. We will not be doing random surveillance or anything like that.” Citing operational reasons, police would not reveal how many drones they have. Without giving a reason, they also refused to reveal how much the program costs. They bought the equipment from Aeryon Labs, a company based in Waterloo that makes “unmanned aircraft systems” for military and police use. Six Windsor officers are trained to operate the drone. They will be pulled from their regular units to run it part time as needed. The drone — police call it a Remotely Piloted Aircraft System (RPAS) — has a two-kilometre range and lasts 50 minutes on a single battery charge. It can fly in light rain and snow, sustained winds of 50 km/h, and wind gusts up to 90 km/h. The aircraft has an optical zoom camera and an infrared night vision camera that pick up movement police can't see on the screen. It is also loaded with software that can reconstruct a crash scene with photos and measurements in 15 to 20 minutes. Other potential uses include search and rescue, taking aerial photos of crime scenes, and helping with marine emergencies. It will also be the eyes for police in dangerous situations such as bomb calls, hostage situations, and hazardous material spills. “The RPAS will assist multiple units within the Windsor Police Service, and it will increase the quality of our investigations as well as help to ensure the safety of our community,” said acting Chief Pam Mizuno. “The RPAS will enhance the Windsor Police Service's response to emergencies and it's going to provide our officers with the ability to lawfully gather intelligence prior to developing safe action plans.” https://windsorstar.com/news/local-news/windsor-police-unveil-new-crime-fighting-drone

    Navy Rushes To Get F-35s on USS JFK; Other Ford Carriers Wait Their Turn

    The service's aircraft carrier boss says the COVID economic slowdown hasn't effected building new carriers -- yet. By PAUL MCLEARY WASHINGTON: The Navy's rushed effort to retrofit its newest aircraft carrier to operate the F-35 will create a testbed for the service's other Ford carriers — which have not been built to fly the fifth generation aircraft — as the Navy juggles work on the remaining three big decks. The $11 billion USS John F. Kennedy (CVN 79) was designed and christened without the capability to fly the 5th generation fighter because of cost caps and the aircraft's infamously delayed development. Those schedule slippages forced the Navy to design and build the ships while the messy F-35 was still undergoing development. In the 2020 NDAA Congress indicated it had had it's fill of delays to the carrier and ordered the Navy to get to work refitting the Kennedy before it sets sail in 2024, forcing the Navy to improvise and refit the just-christened ship. Speaking with reporters today, Rear Adm. James Downey, head of the Navy's carrier programs, said those changes are forcing him to hold off on some early work on the forthcoming USS Enterprise (CVN 80), the third Ford-class carrier, and the USS Doris Miller (CVN 81) to ensure the Kennedy retrofits are done correctly before incorporating them on the other ships which have just started their build cycles. Downey said he's working to accelerate the integration of the F-35 on the JFK and prove out the upgrades in operational testing before doing similar work on the next Ford carrier to be built, the USS Enterprise. That way, all of the bugs will be ironed out on the JFK. The original plan to incorporate the F-35 on the four Ford-class ships was to phase the capability in after the ships were declared operational, and then to refit them as they came into port for overhaul. But Congress, frustrated that the nation's newest class of carrier couldn't operate the nation's newest fighter plane, told the Navy to speed things up. The namesake of the class, the $13.2 billion USS Gerald R. Ford, is currently acting as a training asset off the East Coast, where air wings get carrier certified as the ship continues to iron out remaining issues with its weapons elevators. Simply put, the Ford won't fly the F-35 for years to come. Those electromagnetic elevators have been one of the biggest issues plaguing the ship over the past two years, as the Navy installed them without first testing the new technology ashore, resulting in a ship that had no functioning weapons elevators. And what use is a warship without weapons? It's been slow progress to get them up and running, but the Navy recently certified that just the fifth of eleven elevators is now up and running. The working lifts have logged more than 8,000 cycles over the past several months of operational testing as the Ford acts as the Navy's East Coast training platform to certify pilots. The Ford has been operating one month at sea and one pierside for the last several months, and has launched 2,300 aircraft in that time. Downey said the Ford is keeping to its schedule, and that impending supply-chain issues the services are dealing with as the COVID-19 crisis shutters the global economy shouldn't have any near-term impact on the program overall. “We don't have any real significant concerns right now; we know where the suppliers are,” he said. “Prior to this, we had increased some of our procurements for spares and various materials so we had a pretty steady demand signal.” While the Ford class ships wait for the F-35 upgrades, the 36-year old USS Carl Vinson is undergoing a $34 million refit in Bremerton, Wash. so it can begin flying F-35s by 2021, making the veteran ship the first carrier in the Navy to fly the 5th generation aircraft even before the JFK. While both Nimitz and Ford-class aircraft carriers can operate with F-35Cs aboard, significant modifications are required for both classes to fly and sustain the aircraft for extended periods. Also, the ships will need the capability to push and fuse all the data the F-35s can generate, along with building additional classified spaces, new jet blast deflectors and other refits. Room also needs to be made for Osprey tiltrotor aircraft, which will replace the Navy's C-2A Greyhound fleet that are unable to haul the F-35's heavy engines out to the ship. The USS Enterprise is slated to deploy in 2028 and the USS Doris Miller will be ready to sail in 2032. In January, the Navy awarded Huntington Ingalls Industries' Newport News Shipbuilding a $24 billion contract for the two ships, compared to a predicted cost of $28 billion if the sea service had purchased them separately. https://breakingdefense.com/2020/04/navy-rushes-to-get-f-35s-on-uss-jfk-other-ford-carriers-will-wait
