    A Russian company has developed a Li-Fi system and is marketing it internationaly under the name "Beamcaster"






    Not necessarily, photonic devices basically use lasers to process information within the device, as opposed to electronic devices that use electronic signals to process information. That Li-Fi system is likely an electronic based device.

    The radar is working more or less the same in terms of passing thru the air and hitting the target,
    Photonics here is about high quality/bandwidth signal generation/detection and A/D conversion...
    It isn't otherwise changing the internal processing of the radar system*, just a new means of interacting with radar signal...
    (*besides changes resulting from allowing higher bandwidth and cleaner noise situation)

    Links to work Selex is doing on it...

    Radar waves are already constituted of photons. The photonics and optical computing replace a large portion of the electronics.


    One of the advantages of photonics and optical computing includes free space propagation that provides for parallelism and volume and weight savings.

    How nice would be if another form of cpu could be made and not function on electrons ....thus errors would be eliminate. Also i wanna ask : quantity of photons in particle form can be measured in free space? I mewn outside. Because maibe a radar that measure light would be usefull. Cause sun itself is a big radar.

    Russia to test new over-horizon target detection radar soon — Putin

    The new radar system is designated for operation in the western direction

    KUBINKA /Moscow Region/, June 16. /TASS/. The trials of a new over-horizon radar system designated for operation in the western direction will begin in Russia in the coming months, President Vladimir Putin said on Tuesday.

    "State trials will be held in the coming months to test a new over-horizon radar system for air target detection. It will eventually control the western strategic area," Putin said at the opening of the Army 2015 international military and technical forum outside Moscow.

    Russia will start work from 2015 to create a similar radar system for the eastern direction, Putin said, adding a new radar station started operating in Armavir in the country’s south as of April this year.

    Putin told the Army 2015 forum participants that the samples of combat robots and control systems presented at this arms exhibition would largely shape the current and the future state of the Russian Armed Forces.

    "Their provision with modern and promising armaments is a key task of army development along with the implementation of a large-scale state armaments program and the modernization of the defense sector. We have paid and will continue to pay special attention to this," Putin said.

    When talking about photonics what they are talking about is the replacement of the humble electric cable.
    Electric cables in modern electronics are used for a variety of things including delivering power to things that need power, but one of the other most common use in a computer is to distribute information. Electricity is very inefficient at doing this because it only has two states... on or off, so it has to communicate in binary... in a 64 bit computer that means 64 1s or 0s for each character of data transmitted and it only goes in one direction... one bit at a time. And in one direction at a time. With very long cables there is a delay because the signal has to reach the end before a new signal can be sent.

    Replace that copper wire with a fibre optic cable and you can send whole pages of information in rapid succession without worrying whether the signal has arrived yet or not and it can be going in both directions because the signals wont interfere with each other.

    Obviously you wont be able to solder copper wires, you need and optical sensor and transmitter at each end of the fibre optic to transmit and receive the data... but the speed increases in terms of data transfer will be amazing...

    Russia Deploys New Radar Stations in Arctic


    “We talk a lot about Russia's increasing its presence in the Arctic. The armed forces do not stand aside. As of today, we have deployed new weapons such as Pantsir air defense systems on the islands in the Arctic Ocean; we are deploying new radar stations and fighter jets will arrive there soon.”

    Morpheus, can you plz explain which missiles will be using these AESA radars. Thanks.

    I don't know. I have to measure the dimensions. Without any measurements, I would guess it would fit all of the Buk family and similar-sized missiles. Of course, it can have uses in UAVs and manned aircraft also. The poster next to it may give some clues.

    If the "caliber" was visible, a person would have a better idea.

    The second paragraph in the following clip refers to this radar, not much info though.

    By the way, to the right of the MAFAR, there seems to be a 3 mm (millimeter wave) datalink (guessing) named Эдельвейс (Ehdel'vejs, as in edelweiss).

    The 3D L-band radar/IFF array is very well visible.

    i know ho errors of any radar can be resolved. different frecvency pulses and diferent time of pulses. in this no matter if the signals that are coming back are mixed.
