    air defense missile system S-75-2 Volga-2 The exhibition" MAKS-2001 "Scientific and Production Association" Diamond "presented a modernized version of the anti-aircraft missile system S-75 (" Volga "), which is currently in service with defense forces dozens of countries. This project has received the designation C-75-2 "Volga-2".

    Modernization SAM "Volga" to the level of "Volga-2" provides for improving the characteristics of the complex, providing a successful struggle with modern means of air attack in a complex interference environment through the use of technology and the elemental base of S-2-300PMU1. < / p>

    air missile system S-75-2 provides defeat bombers, strategic bombers, fighter-bombers, aircraft, multi-purpose, high-speed reconnaissance aircraft, automatic drifting balloons and cruise missiles with radar cross section of 0.2m2 and more.

    Composition

    air defense missile system S-75-2 Volga-2 The system consists of air defense missile system (ADMS), anti-aircraft missiles (SAMs) 5YA23 or 20D and logistics facilities.

    SAM includes the following basic facilities:

    tracking radar and guidance PGH 75V placed on three trailers (transceiver, control appaparatnaya cabin). RSN_75V has radar and television channels escorts working in automatic and manual modes.

    Six launchers with one rocket on each.

    Power Tools.

    -channel complex on purpose. Additionally, SAM can be given radar detection and targeting P-12 and P-15. Funds placed in the SAM transported trailers and semitrailers, the relationship between them is carried on cable. Electricity industry - from mobile diesel-electric stations. You can connect to industrial networks.

    air defense missile system S-75-2 Volga-2

    Zour 20D and 5YA23 - staged, performed by the normal aerodynamic scheme destabilizers in the front. The first stage is a solid rocket motor with installed stabilizers, second - is equipped with a liquid-propellant rocket engine pump fuel supply system components. Structurally sustainer stage consists of a number of sections in which there are radio controlled fuses, high-explosive warhead, blocks on-board equipment, tanks propellants, liquid rocket engine, rocket units uparvleniya rudders, receivers,.

    The launch

    - reclining, with launcher, induced elevation and azimuth. Flight control and missile guidance to the target is carried out by radio, coming from a ground station targeting and undermining warhead - team of radio controlled fuses or under command from the ground station when approaching the target to the required distance.

    Modernization SAM carried out using technology and element base S-300PMU1-2 and includes:

    improving the security target channel.

    introduction of sound indication purpose mode RLC.

    introduction of the target auto-tracking mode TCEs.

    replacement by digital equipment following analog computing devices:

    O device positioning and target missiles (CRM);

    O generation commands missiles (JMC);

    O automated trigger device (APT);

    O subtractor MTI;

    O devices demodulation interference (GSHV);

    O synchronizer station;

    O equipment training and monitoring.

    This will increase the accuracy of the missile guidance and distance hitting the target, through the use of a new method of missile guidance and optimal signal processing method targets and missiles. Furthermore, the amount of equipment in the cubicles HC and AB is reduced by about half.

    From

    of HC and AB found 66 blocks of 135.

    The upgrade will PGH 75:

    RLC mode:

    O to detect, track and direct missiles at targets going undercover ACP background DNA with a density equivalent to 2000vt/Mgts Ke = 100km range throughout the affected area SAM at the active site of the missile;

    O range to perform an autopsy director ACP within the affected area at the active site of a missile by devices of coherent storage and algorithms ties trails in NE;

    O to detect, track and direct missiles at small targets and goals of "STEALTH" throughout the affected area SAM at the active site of a missile by increasing the sensitivity of station mode coherent accumulation at ~ 16dB;

    O increase range target detection and tracking;

    O eliminate the influence of "Mestnikov" and meteorological formations located on the second scan range mode MTI;

    O increase the range up to 60km shelling purposes;

    O increase the effectiveness of fire by increasing the accuracy of the calculations, eliminating drift "zeros", the application of optimal signal processing techniques and missile guidance to the target;

    O provide target tracking coordinates sustained in the case of temporary loss of visibility targets in RFCs or TCEs;

    O for an automatic control of the newly introduced digital equipment and the fault up to a replacement element.

    TCE mode:

    O produce (consistently) automatic acquisition of targets (up to 2);

    O automatically accompany the chosen target, determining its angular coordinates of the center of the screen up to 0.02mrad;

    O determine the mode MW target height above the horizon, thus increasing the accuracy of the missile guidance on low-flying targets, and therefore increase the likelihood of their defeat.

    After upgrading

    improved performance PCH-75

    reducing the number of attendants;

    reduces power consumption by 40%;

    improved ergonomic working conditions officer guidance on indicators by deducing information about the coordinates and parameters of target motion, the formation of "a guaranteed kill zone";

    partially automates guidance officer;

    increases the reliability of the RDA;

    decreases the time and the amount of maintenance work;

    Availability of replacement training programs calculate RSN in the software spetsvychisliteley significantly expands the possibilities of learning and training operators MS officer pointing and shooting.

    The upgrading cabins HC and AB may be made by the customer, or in places where on a production basis.
