SA-6 "Gainful" (KVADRAT)
Original SA-6 SAM system (2K12 KUB / KVADRAT) is a mobile short range Surface to Air Missile system that consists of missile launcher vehicles SPU and radar vehicle SURN. All vehicles are based all-terrain tracked chassis. SURN system performs searching function, low altitude acquisition, target tracking and semi-active missile guidance.
SA-6 system modernization eliminates original system limitation consequent on outdated technology. All obsolete equipment and components with limited availability are replaced by modern, high performance and latest standards compatible subsystems.
The modernization of SA-6 system enables an interoperability with up-to-date AD C&C systems, increase system combat performance and reliability.
The proposed modernization includes:
- New microwave circuitry
- New high performance all solid-state receivers
- New transmitters
- New adaptive radar signal processing
- Optical channel upgrade (fire control radar)
- Original analog indicators replacement by new multiple-function color displays
- United display of local air picture and data received from superior system (commander's console)
- Combined display of fire control radar and optical channel (fire-control radar operator)
- New Mark-XII compatible IFF interrogator and antenna New tactical VHF transceivers for voice communication and data exchange
- New digital intercom
- Data recorder
- EMC filters avoiding jamming of FWA networks
- New tracks with high performance rubber pads
- New camouflage painting
The extended SURN CZ functionality enables replacement of KPC vehicle
The modernized SA-6 system successfully attended on Live Fire Exercise in 2001, 2007 and 2009.
SA-13 "Gopher"
The SA-13 „Gopher" (S-10 Strela) is self-propelled VSHORAD surface-to-air missile system, intended for firing of the low/medium-level air targets. Manual operation and original incompatible communication, navigation and identification means make impossible to fulfill today's requirements imposed upon this kind SAM systems.
Submitted modernization consists of
- Up-to -date radio and line communication interface to link system with any C4I Center
- Commander terminal
- Automatic target handover into missile fire
- Control system
- Up-to-date IFF Mark XII interrogator with new antenna
- Hybrid INS/GPS navigation system
The air picture information that is delivered from external radar data source by means of the wire or radio link is depicted on the Commander terminal. The Commander terminal is supported by hybrid navigation system. The target clicked for fire is automatically aimed and the target identification is ultimately verified just before missile launch.
The modernization upgrades SA-13 SAM system fire effectiveness, shortens reaction time and minimizes thread of friendly firing.
SA-8 "Gecko"
SA-8 „Gecko" (9M33 OSA AK/AKM) is a mobile short range SAM system with command missile guidance. System employs all sensors and missile launcher on one amphibious off-road vehicle.
The highly appreciated efficiency of SAM system based on extremely high mobility and performance of missiles suffer from aged radar electronics and lack of integration into AD command systems.
The severest limitations of original system are:
- Outdated communication subsystem
- Obsolete radar signal and data processing
- Lack of electronic protection functions (ECCM)
- Limited capabilities of analogue indicators
- Incompatible IFF system
- Low reliability
To achieve up to date system performance and extend lifetime is necessary to upgrade functionality and reliability bottlenecks of radar system. The scope of upgrade can be modified upon user's requirements, while some essential subsystems are mandatory.
Proposed upgrade of SAM system's radar achieves interoperability with air-defence command and control systems, increase system combat performance and reliability. The proposed upgrade includes (in all channels of surveillance and fire control radars):
- New microwave circuitry
- New high performance all solid-state receivers
- New transmitters
- New adaptive radar signal processing
- Upgrade of optical channel (fire control radar)
- Replacement of original analog indicators by new colour displays
- Up-to-date Mark-XII compatible IFF interrogator (including antenna)
- New fire control computer, missile tracking receivers and signal processor, upgrade of missile command link (coder unit)
- New tactical VHF transceivers for voice communication and data exchange
- New digital intercom
- Data recorder and integrated simulator means
- EMC filters avoiding unwanted emission in spurious and out of the band domain
- Overhauling of original special electronics preserved in system
Suggested upgrade can be gradually structured depending on user requirements, military authority policy, budget priority, etc.
