    air defense missile system skyguard-sahv Fire Control System" Skyguard ", established in the late 70s, to date, has gone through several stages of modernization and in the various air defense systems is the army has many foreign countries: Argentina , Austria, Canada, Egypt, Greece, Malaysia, Saudi Arabia, Oman, the United Arab Emirates. It is designed for the collection, processing and analysis of data on air enemy operating at low and extremely low altitudes, as well as for remote fire control means of fire damage (anti-aircraft guns and missiles).

    High performance, an interface to a variety of firepower and the extensive use of "Skyguard" in the armies of many countries have provided the ability to create on its basis of modern anti-aircraft missile and artillery systems (SPAR) with minimal cost and in a relatively short period of time. Swiss firm "Oerlikon Contraves" together with the South African company "Kentron" highly developed SPAR - "Skyguard-SAHV". The complex used remote-controlled twin 35-mm anti-aircraft guns GDF modifications 002, 003 and 005 firms "Oerlikon Contraves" and anti-aircraft guided missiles SAHV-IR (South Africa).

    most likely potential customers complex "Skyguard-SAHV" is considered the South African army, having armed Zour SAHV-IR and a large number of guns GDF, managed by an outdated system "Super Fleder-mouse." In addition, according to experts, it has a very high potential for sale on the world arms market.

    Composition

    The complex "Skyguard-SAHV" include:

    fire control system "Skyguard-II"

    one or two launchers with anti-aircraft guided missiles SAHV-IR (Surface-to-Air High Velocity - Infrared)

    two 35-mm anti-aircraft automatic guns.

    All elements in the transport position towed road vehicles.

    system has high noise immunity thanks to the combined use of many technical solutions, the main of which are wide tuning range frequency of the signal surveillance radar airspace, processing data from multiple detection tools, performing its functions in different regions of the electromagnetic spectrum, and the payment of clutter. It is equipped with equipment start-up warnings about anti-radar missiles. Founded in her fire-control algorithm enables the optimum firing simultaneously two or more goals antiaircraft guns and SAM.

    The system "Skyguard-II" include:

    Pulse-Doppler radar detection of enemy air attacks (frequency range 8.5 - 9.6 GHz) is used to review the airspace at a range of up to 20 km, threat assessment, identification of identified goals and 20 simultaneous tracking of them, and for target designation means tracking (radar or electro-optical module) and fire damage. Transmitter station output amplifier which made traveling wave tube has 25kW peak power and 200W average. Frequency probe pulses and their repetition period is automatically set depending on the interference environment. Horizontal polarization of the emitted signal. The antenna station (rotational speed of 60 rev / min) is formed as a segment of a flat cylinder. Its width pattern is 1.3 "in azimuth and 30" in elevation.

    monopulse radar target tracking (range 18 km) provides air support means having radial velocities close to zero, and directors jamming in their bearing. Operates in the same frequency range as the radar detection, as through a directional coupler is connected to a common transmitter. Withdrawal from the transmitter to its antenna device (beamwidth 2.4 °) 50 - 90% of the power generated automatically after the capture targets for support. To process the received signal in the station used Doppler filtering, pulse compression, compensation clutter and stabilization of a false alarm.

    Optoelectronic module consisting of a television camera, able to work at any time of day, and a laser rangefinder. It allows passive reconnaissance aerial targets and guide them through the three coordinates (azimuth, elevation and range)

    Point fire control. It consists of a digital computing system based on the processor "Bark" MI chief of calculation and remote operator, equipment and data communications equipment. Equipment item has a built-in control, allowing time to troubleshoot and repair them. To one control point can be connected to four firepower. Communication with them is carried on digital (radio) or a two-wire line. Fire control point has a high degree of automation.

    All equipment is placed in a uniform cabin, which can be mounted on a biaxial towed trailer, truck or armored personnel carrier.

    air defense missile system skyguard-sahv

    High-speed single-stage solid-fuel

    Zour SAHV-IR is based on the normal aerodynamic scheme and equipped with high-explosive fragmentation warhead, which is produced by laser blasting fuse. Engine Fuel kitted with reduced smoke and with SAM achieves maximum range (8 km) for 14 seconds. Anti-aircraft guided missile has a relatively large total weight that according to developers, helping it to maintain airspeed reached after engine stops running. In addition, it can be equipped with a weighted warhead, providing the most effective engagement of targets of different types.

    missile guidance to the target by using a passive infrared seeker, created on the basis of the GOS aviation SD "Darter" class "air - air". It works in two areas of the IR wavelength range: 3-5 and 8 12mkm. Capture striking targets (angle 100 °) produces both GOS when the rocket on the launcher (to start), and during its flight to the target. In the first case, the shooting is on the air over a distance of no more than 3 km. To engage targets located at a distance of 3-8 km, uses the second method, which consists in the following. SAM runs in the intercept point, determined according to radar tracking and flight control to capture head hit targets by using the onboard inertial measurement unit based on the input it before the start of the program. When you hover Zour SAHV-IR method is implemented on the target proportional approach and the principle of "shot - forgot" that under certain conditions, allows simultaneous multiple intercept enemy air assets.

    Rocket is in a sealed transport launch canister (TPK), weighing 45 kg, from which it is removed only for periodic maintenance and repair. TPK has a rectangular shape, which, according to developers, gives it a unified character and allows you to place on different launchers. At SAM launcher, which is mounted on a gun carriage gun Swiss GDF-005, located eight missiles in TPK. Command fire control system "Skyguard" it automatically turns towards the target to be destroyed. To cool sensitive components GOS launcher positioned cylinders filled with liquid nitrogen.
