    KUBINKA /Moscow Region/, August 24. /TASS/. Russian-made radar Rezonans-NE, which Iran purchased to identify and track stealth aircraft and hypersonic targets, successfully spotted and tracked US F-35 fighters near the country’s borders during an aggravation of tensions at the beginning of 2020 following the death of Iranian General Qasem Soleimani, the deputy CEO of the research center Rezonans Alexander Stuchilin told TASS on Monday.

    "At the beginning of 2020 this radar identified US F-35 planes and tracked them," he said on the sidelines of the international military-technical forum Army-2020.

    Stuchilin said that he was referring to the "well-known events of the beginning of this year."

    "The radar’s personnel were transmitting information, including the routes of F-35 flights, in clear, thus confirming that it was reliably tracking the planes. For this reason, the opponent did not commit any irreparable actions that might have caused a big war," Stuchilin said.

    He remarked that the Rezonans-NE radar had been on round-the-clock combat duty in Iran for several years.

    The situation in the Middle East aggravated sharply after the January 3 US overnight attack near Baghdad airport, which killed the commander of Quds Force of the Islamic Revolutionary Guards Corps, General Qasem Soleimani. Tehran retaliated on January 8 with an overnight missile strike against two targets in Iraq that were being used by the US military: the Ain al-Assad base and Erbil airport.

    Renowed Concern Вега has completed tests on the first prototype demonstrator within the program РОФАР.

    The tests have proved the computed characteristics and allow to foresee theirs implementation directly in the external structure (smart skin) of aviation, naval and space equimpent.

    Mindstorm, I know you've talked quite a lot about ROFAR and its associated technologies, and I wanted to ask directly, is the investments made into the ROFAR program applicable to optical computing? I know there was photonic circuits was a part of the program, but are these types of circuits useful in the creation of a optical processor? From my limited understanding, these photonic circuits are used in processing data for the ROFAR itself, could this translate into a commercial/marketable product in order to expand Russia's economy and standard of living for its citizens by breaking the American stranglehold on the rest of the world by controlling Intel/AMD and all its associated technologies?

    Most definitely. I said it before and I'll say it again, the secret to ROFAR is in fact photonic computing. Kret's director (Vladimir Mikheev) has said that the 'technologies' behind ROFAR could just easily be applied to Sonar. [The original Kret link was deleted]

    He also stated that in the future the ROPAA technology will be used on the newest submarines. “It is quite possible that we can see underwater as well. We are considering the technology’s applications as submarine sonars”, Mr. Mikheev noted.

    https://www.deagel.com/news/n000014838

    Let's put this to perspective. Radar and Sonar work on radically different physics principles respectively. Sonar travels faster the denser the substance it travels through; sound waves travel at orbital speed through diamond. On the other hand electro-magnetic radiation diffracts greater when passing through denser substances. This is why astrophysicists have suggested using water to insulate interstellar space craft from gamma radiation, and this is also why ELF wavelengths are one the few reliable ways to communicate with submarines. This is also the reason why smoke grenades in T-72B3/T-90A's are effective, as the aerosol stored in the grenades are aluminum-silica microspheres infused, which effectively absorb almost all forms of electro-magnetic radiation. The potential Sonar application for 'the technologies behind ROFAR' discredits the idea that it's simply radar technology, and supports the idea that it is in fact computing technology, which is the most important factor behind ROFAR.

    Some people have incorrectly likened it to LIDAR, but this isn't correct as Mikheev has stated how it functions:

    At the same time, the use of ROFAR will reduce the visibility of aircraft in the infrared range and significantly save fuel. All modern devices, converting microwave energy from ordinary 220 volts, have an efficiency of 20-30%. With 20% efficiency, we have 80% of the heat that needs to be hidden somewhere, so modern airborne radars require heavy and energy-intensive cooling systems.


    When converting optics in a photonic crystal into microwave radiation, the efficiency can be 70, 80, and even 90%. Here this problem was solved initially.

    https://vpk.name/news/147516_vladimir_miheev_nashi_uspehi_neskolko_podtolknuli_amerikanskii_vpk.html

    Some 5 years ago I posted from Kret's website (which was later deleted) which heavily suggested the civilian uses for the technology behind ROFAR. They suggested using photonic computers along side fiber-optic cables modified in to heating elements to heat homes to near 100% efficiency. The deleted article also stated that the domestic (Federation) information/tech economy would greatly benefit as they could shrink processing centers required to power major companies (such as Amazon, Google, Microsoft, etc.) from massive warehouses full of mainframes, in to spaces the size of relatively large living rooms. The implications would mean a financial, powering and cooling cost reduction by orders of magnitude. Those applications of 'technology derived from ROFAR' all have nothing to do with radar whatsoever.

    Thanks for good news, now besides RTI and KRET this will be the 3rd company I will be watching regarding the news.

    Can we get a list of the companies and their ROFAR products listed?

    KRET- We have a prototype photonic radar thus was announced to have fully been created in 2018. Hoping to get military related equipment to be ready with such radars in the 2020s.

    RTI- Have worked on PICs like a photonic radar balloon that I have posted in the past. Said they already created it and that the army would soon get it. Only company of the 3 to make announcement on starting production for PICS between 2021-2023 I believe in my previous 2018 article they stated 3-5 years.

    VEGA- Says they created a photonic radar.

    Only 3 military related companies I can think of.

    I wonder if there is a chance for the ROFAR radar on the modernized T-50 of the second stage? From what these radars write, it will be a revolution that will change a lot on the battlefield. If he really sends the stealth technologies to the bin.

    So what does this Rofar emit ? Lasers ? or some form of other rays ?.

    ROFARs are standard radars except built on on photonic circuits rather than electron based circuits, with resulting vastly superior performance due to photons not having mass.

    Instead of using a solid-state waveform generator feeding into a amplifier as todays electronics, you instead have a special laser and crystal that produced the waveform, with better efficiency, mass, and ability to significantly expand available bandwidth.


    Take for example the three radars of the Nebo-M series, VHF/L/S&X band AESAs and there associated command platform that fuses all their raw data into one refined "picture", a ROFAR could outperform all three radars combined(It could emit in those bands and more near simultaneously), and be smaller and lighter with less power draw and heat generation, due to the expanded bandwidth feature.

    So it's basically a Photonic True Time delay AESA where the waveform from the master oscillator is "fed" to the each Transmit Receive Module via optic fiber ? Thus it is not a "Quantum Radar"

    The TRM the re-convert the laser to RF wave and emit it as usual ? The beamsteering is instead of phase shifter (which bottlenecks the bandwidth) Is done through the optic fiber which cuts into different length representing the phase required for the beamsteering.

    Whats the difference between LIDAR, chinese quantum radar, and ROFAR?
