Lockheed Martin has begun to test promising radar

32
The American company Lockheed Martin has begun testing a reduced prototype of a promising radar station for the selection of ballistic targets LRDR (Long Range Discrimination Radar), reports "Nplus1"Post Breaking Defense. On the prototype, technologies for detecting and identifying ballistic targets and their subsequent separation into true and false ones are being worked out.


Countries with nuclear weapons weapon, are engaged in the creation of new combat units for ballistic missiles that could break through the missile defense system. Such combat units will be equipped with maneuvering nuclear units and false targets, which for radars will be practically indistinguishable from the units themselves.

As specifies Defense News, in parallel with the beginning of the test LRDR, Lockheed Martin defended its draft design. The new radar station is expected to start operating in 2020 at Kliar Air Force Base in Alaska. Its construction is scheduled to begin in 2019.

According to the project, LRDR radar will be created on the basis of gallium nitride. The use of this material will significantly improve the signal-to-noise performance compared with modern radars based on gallium-arsenide. As a result, with less power consumption, the radar will be able to detect air targets at long range and altitude.

Prospective radar will work in wide-angle modes of visibility - to detect targets and a narrow angle - for accurate recognition and tracking. The station is planned to equip with protection against electronic jamming. LRDR will be connected to the US national missile defense system. In particular, target designation from the radar will be transmitted to anti-missiles in Alaska and in California.

Currently, the American missile defense system includes three early warning radar and early warning radar PAVE PAWS. In addition, the United States has a sea-based SBX mobile radar station operating in the X-band.

      The American company Electric Boat is engaged in the refinement of submarines such as Virginia to adapt them to women sailors. According to Navy Times, the company plans to redesign the internal layout of the ship. As expected, the first submarine, built with the expectation of women submariners, will be the "New Jersey", not yet laid down, but already ordered by the military ship.

      All modern submarines were designed exclusively for men's crews. For this reason, some elements, including bypass valves, are designed for male power; turning them into women can be difficult. In addition, showers and residential compartments were also designed for men only.

      According to the statement of Electric Boat, in addition to the obvious increase in the number of showers on the submarine, the organization of separate latrines and beds, the company intends to change some other elements. In particular, most of the high controls will be moved lower, making them easier to switch or rotate.

      In addition, the company intends to install ladders in three-tier beds to make it easier for women to climb the second and third tiers. Finally, all information signs and displays will be placed below. As expected, the submarine "New Jersey" with the new layout will be part of the US fleet in 2021 year.

    It is not clear where the Russian intelligence systems are. Now is the time to take the frequencies and parameters of the signals, analyze the operation modes. After 2 years, the radar will enter service, for engineers developing jamming systems to guarantee that missile defense is short of time.

        Not necessary. But the simple fact that it is maintained, that information is collected and summarized is incredibly reassuring, good insurance against surprises. Especially after the UN extreme report on the increased danger of an "accidental" nuclear war.

      the frequencies are the same, parameters (there only the power changes)
      GaN transistor is different
      -higher performance
      - can combine several important electronic functions on one chip more efficiently than conventional solutions
      - will reduce the physical size of equipment
      - consume much less energy than their silicon counterparts
      -GaN transistors are distinguished by increased survivability. Not only are they not afraid of either heat or cold, they feel comfortable even in conditions of increased radiation background.
      This is important for both anti-aircraft missile defense and CVC radar.
      but in essence (the frequencies and principles of radar do not change).

        In fact, it’s interesting that no one ever says that frequencies and other parameters are not stable. But it is their formatting according to transformation algorithms that depends on the changing properties of the atmospheric portions and makes it possible not to increase the transmitter power, but to harmonize the pulse during it " displacement. " Moreover, it is the transition to higher frequencies and other parameters of the modified signal amplitude that makes this signal itself independent of the enemy. Of course, until the enemy began to work in the same parameter of the signal properties. Therefore, it is extremely important who will achieve such results at a faster pace and will dominate in competitive conditions.

    I read and imagine: the Americans are sitting with a soldering iron and a file and made of Ni-Ga crystals

    "create" a new radar


    maybe still
    LRDR radar station will be created on new anti-missile defense based on galium nitride

      A false warhead, as I understand it, is a cone that is exactly equal in size to a real warhead,
      but empty inside. And because it is empty and light, several of these cones can be compactly placed on the “carrier” of warheads, without greatly increasing the mass of the missile being thrown.
      The Americans are trying to improve the radars of the "kinetic killers" - devices ramming warheads, so that they distinguish the empty cap of the BR from all sorts of small signs
      complete.

        Do tanks also protect with false shells empty inside the size of a tank? In order to get the same “response” in the radio range, only the corresponding reflectivity is needed, while the false target has smaller dimensions and, accordingly, less mass, to create a similar trajectory. The differences are too minimal to pinpoint who is who. hi

      One can only state, based on the information presented, that these are completely primitive methods of construction. Understanding of how magnetic force interactions are formed is completely, apparently, not of interest to designers. But in vain.

    Lockheed Martin, having this gallium nitride technology, modernizes not only this missile defense component, but also a whole range of systems.
    21.07.2016
    Lockheed Martin has responded to a request from the US Army to update the Patriot radar in the LTAMDS (Lower Tier Air and Missile Defense Sensor) program, Military Parity reports.

    The new radar should replace the existing radar, have a higher situational awareness and at the same time lower operating costs, high transportation mobility, reliability and affordability. “This request by the US Army suggests that it recognizes the existence of some technical flaws in the Patriot radar equipment and its aging. We welcome the opportunity to apply our new technologies that will address system flaws, ”said Tim Cahill, vice president.

    Lockheed Martin is the only American company that produces radars with an active phased array for air defense systems and the only one that uses gallium nitride (GaN) -based technologies for the production of radars, including for export. The company is investing $ 3 billion in technologies for the MEADS (Medium Extended Air Defense System), Space Fence (S-band), Long Range Discrimination Radar (LRDR), 3D Expeditionary Long Range Radar (3DELRR), AN / TPQ- 53 and Aegis.
    It is noted that this program at a cost will be much cheaper than a comprehensive modernization program of the complex. Https: //vpk.name/news/159790_petriot_mo

    These "dreamers" will not spare any money, especially since it is not their personal money, but simple-minded citizens of the country to finish off the remnants of the Russian state, as they once invested in the collapse of the Russian Empire, and then the USSR. As they say, do not wash so skating! But they forget about the existence of a simple principle - everything complicated is easier to break simple! hi

    It is an empty lesson to recognize false warheads ... absolutely empty ... I recall that even Soviet ballistic warheads were equipped with false targets which, in 35 parameters, FULLY corresponded to the behavior of real warheads. Well, let’s put the flag in their hands and let’s saw "they are golden." As they finish it, they can and will understand what's what.
