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/

Burak Ege Bekdil ANKARA, Turkey — The Canadian government's decision to suspend export of key drone parts to Turkey has once again thrown a spotlight on Turkey's ongoing efforts to develop a self-sufficient defense industry. Turkish President Recep Tayyip Erdogan often boasts at party rallies that his governance since 2002 has reduced Turkey's dependency on foreign weapons systems from 80 percent to 30 percent. There is truth in that, although the actual percentages remain a mystery, mainly due to the difficulty of defining what is truly a local or national system. Most Turkish “national” systems depend on various degrees of foreign input, often including critical parts only available abroad. The T129, an “indigenous” attack helicopter, is a Turkish variant of the Italian-British AgustaWestland A129 Mangusta chopper. Turkey's local industry has no engine technology. The “national” new generation tank Altay is facing major delays, due to the lack of a foreign engine and transmission system. Turkey's first “indigenous” landing platform dock, the TCG Anadolu, will enter into service next year, but the $1 billion or more ship is being built under license from Spain's Navantia. Even Turkey's biggest success in the past few years, a locally-built drone known as the Bayraktar TB-2, features critical foreign parts — an issue now in the spotlight following Canadian Foreign Minister Francois-Philippe Champagne's Oct. 5 announcement to suspend export permits of drone technology to Turkey, which is backing Azerbaijan in the recent Azeri-Armenian military conflict. Champagne issued the pause in exports alongside an order for his ministry to investigate claims that Canadian drone technology is being used in the fighting. The decision followed an announcement by disarmament group Project Ploughshares, which warned the multimillion-dollar exports of high-tech sensors and targeting technology produced by L3Harris WESCAM in Burlington, Ont., are in direct contravention of Canada's domestic laws and its international obligations under the United Nations Arms Trade Treaty, to which the Trudeau government acceded almost exactly a year ago. L3Harris WESCAM, the Canadian subsidiary of U.S. defense giant L3Harris, is one of the world's leading producers and exporters of electro-optical/infra-red (EO/IR) imaging and targeting sensor systems — both of which are featured on the Bayraktar drones. “These sensors are integral for their ability to conduct drone warfare, which they've done increasingly... in the past few years across several conflict zones,” Kelsey Gallagher, a Project Ploughshares researcher, told Radio Canada International. “If the exports of these sensors were completely halted, then Turkey would not have the sensors necessary to conduct modern airstrikes.” “This [the suspension of Canadian supplies] may cause disruption in the production line,” said one local aerospace analyst, “unless substituted immediately.” “There may be some other foreign suppliers to be used as a stop-gap solution," the analyst added. "But this is mostly a Western (including Israeli) technology and may not reach Turkish manufacturers due to political reasons.” Turkey's top procurement official, however, has a solution. Ismail Demir, president of the defense procurement agency SSB, twitted Oct. 6, the day after the Canadian decision, that Turkey would soon start to mass produce the CATS electro-optical system, to replace the WESCAM technology used in the TB-2 drone. CATS will be produced by military electronics specialist Aselsan, Turkey's biggest defense company. Demir said that Aselsan has also begun to work on developing a future version of the CATS system. Demir also talked up another new indigenous ambition: Project Özgür, or “free” in Turkish. Özgür is part of a broader upgrade effort designed to extend the life of the Turkish F-16 fleet. “This program aims to completely nationalize electronic systems on our F-16s,” Demir told the HaberTurk newspaper Oct. 6. The full upgrade work will also involve structural and avionic modernization. Turkey views the F-16 upgrades as a stop-gap solution before it builds its own indigenous fighter, the TF-X. But the TF-X effort has moved at a crawl, with no notable progress in the past few years, due mainly to the lack of an engine to power the planned fighter. https://www.defensenews.com/global/europe/2020/10/13/canadian-block-on-drone-parts-shows-turkeys-defense-industry-still-not-independent/
